Title: complementary analog / digital effects
Post by: lcbzh29 on November 19, 2017, 12:21:38 AM

Hello

we can only use one effect per layer on the rev, that will advise you as additional analog or digital effects to add to the prophet (pedal, rack, reverb, chorus, delay ...multi effects)

Thank you for your answers

Sorry, I did not find any question to which you want an answer. I agree, if you need more effects you will have to use external ones.

You can indeed only use one effect per layer on the Rev2. In my case I often find the on-board effects on the Rev2 sufficient for what I want to achieve. I find the core (oscillators) sound of the Rev2 very good en very musical, sometimes effects are overkill.

In case I do want some additional effects I mostly use a Lexicon MX400 unit. The advantage of the Lexicon is that it has two independent stereo effect channels. I can route each layer of the Rev2 independently into the MX400 channels and assign different effects to each layer.

I hope this is an answer to your question, the choice of words you used in your first comment in this threat is not entirely clear.

I am trying to create a "shimmer"  like effect using the MX400, but that is a bit more difficult than I thought. There is a pitch shift effect build into the MX400 but it doesn't play very nicely with the build in hall-room-reverb(s). I did achieve a reasonable effect sound using the following serial effect trail:
mono delay on the Rev2 --> pitch shift one octave on the MX400 --> large hall reverb on the MX400
It sounds OK but not quite what I wanted.

I think he's asking, in lieu of the serviceable effects block in the Rev 2, what external ones do we use.

I use the Rev 2 with a DAW so I have a lot of plugins I like for eq, comp and effects, but for the Rev 2 (and other prophet-like synths). I like to use EchoMelt from PsyMod.  It's a really good multi with delay, chorus, parametric eq, and a really useful tape saturation and pitch shifter.  It's marketed toward people who are obsessed with lo-fi era stuff but It's also inexpensive and has a pretty warm character.

I generally do Ambient music, so I need a reverb of a VERY high quality on most of what I do... something that very few synthesizers have built in.... thus I use a Lexicon - PCM92 for setting the space environment for the score I'm doing.

This is actually the most logical way for me because I would need all synths to have the abillity to go through the same reverb to make them all sound like they are coming from the same environment.

This leaves the REV2 Reverb as not much used in my case, even though a reverb on a reverb can be useful... I generally use the build in effects in synths more for modulation purposes... chorus, flanger, phaser etc... as a sound sculpting building block so to speak... delays are nice to have on the synths in this case because that will also put reverb on the delays... again to keep everything in the same environment.

I have one more external FX engine on the "wish list" for the future... an Eventide - Eclipse... mainly because I miss that the PCM92 could do a Shimmer Reverb... (one where a delayed pitch shifted wet reverb signal is fed back into the reverb itself)...

OK guys,

Not for Rev2 at the moment, but it can be connected easily if needed: Blofeld and strymon BigSky, Doepfer Dark Energy and ZOOM MS-70CDR. The Lexicon MX400 is indeed on my "gear-to-buy" wishlist. Razmo's gear is high end, looks really fine, so you I think should find something...  8)
Title: Re: complementary analog / digital effects
Post by: Razmo on November 19, 2017, 09:37:51 AM
I had MX400 earlier... a very fine piece of equipment if not one of the best, in the budget range if you want rack-mount gear... it can also be configured in quite a lot af routings, and can have up to four engines running at the same time, and the Reverbs are really good too... I used this one before I got my PCM92... I would choose it again, if I needed a low budget external rackFX.

Thanks Razmo, you gave me the answer in creating a nice shimmer effect using the MX400: like Brian Eno did years ago. Feed the output of effect channel of one layer of the MX400 back into the input of the second layer. So now it looks like this:
Rev2 delay -> MX400 layer 1 large hall --> pitch shift + 1 octave --> MX400 layer 2 large hall --> chorus

This gives me plenty scope in experimentation, I totally forgot my mixer had the ability to do this.

Speaking of pitch shift and reverb, If I watch this thread long enough I wonder if someone will happen along with audio examples of the Rev 2 through an Eventide H9000.

All the onboard effects fit my needs aside from the most important one, the reverb. Thus I picked up a Boss RV500 that I keep active at all times because it adds an extra dimension to the overall sound.

Gerry Havinga:”I am trying to create a "shimmer"  like effect using the MX400, but that is a bit more difficult than I thought.”

*sorry for weird quoting, first forum post*

Using only my Rev2, I used one of the LFO’s to modulate the Reverb in Effects. I assigned the LFO to Param1 of Effects, and with a bit of tweaking of the LFO wave type and values, and both on clock sync, I got a shimmering Reverb effect that I get on my bass guitar when combining 3 stomp boxes: MXR Reverb (on PAD) + BossBassChorus + Boss BB1X (with subtle Overdrive).

Wow James, I will try that tonight, thanks for the great tip  8)

I am getting closer with the MX400 and creating a feedback loop using my Soundcraft mixer. Very easy to blow up the speakers like that, ha ha, great fun anyway ;-). Can make it loop for minutes as long as I carefully choose the correct sound / tone / note to begin with.
Title: Re: complementary analog / digital effects
Post by: Razmo on November 28, 2017, 12:06:40 AM
A real shimmer FX is done by taking the WET reverb signal, route it into a pitch shifter (1oct up)... then delay this pitch shifted reverb for some time (to make it gradually introduce itself), and then finally feed this delayed, pitch shifted wet reverb signal, back into the reverb input.

The pitch shifted and delayed signal should NOT be mixed into the main mix, it is only meant to be routed back into the reverb input... with different send levels back into the reverb, the effect will vary in strength.

It does require some tweaking to set it up, if you do not have a dedicated shimmer FX though... a good software plug for the Shimmer FX is Valhalla Shimmer... then you do not need to think about all the routing requirements.

It's impossible to create this using the FX engine in DSI products... not enough FX slots, and routing options at all, it is not even possible doing it with either MX400 or even PCM92... the key is that you need to be able to pitch shift and delay the reverberated signal "off line" (these processes should not get to the main out), and then route it back into the reverb, and this routing is not obtainable in many FX units on their own... they simply do not allow the feedback routing option, and the parallel processing of the wet signal after the reverb.

It can be done using mixer channels with pre AUX sends:

connect the stereo output of your main reverb unit to a single stereo input channel on your mixer.
send a portion of the returned wet reverb via AUX send into another FX processor that can pitch shift the wet reverb and delay it.
connect the wet signal of this FX unit to yet another stereo channel on your mixer, set this channel to be pre fader send, and turn it's volume all the way down so that it does not enter the main mix.
now send a bit of this channel back into the reverb input by using the channels AUX send to the reverb.

That's basically it... but be careful with the controls... there are many possibilities that will lead to ear shattering feedback loops ;)

Razmo, Thanks for the excellent description.
Now I know what Boss (with “shimmer” on their Reverb) and MXR (with PAD on theirs) have tried to do. BTW, I have both and the MXR has a less of a digital sound: to my ear, if anyone's interested in a stomp box reverb with this "shimmer" effect.

But for those of us looking for ways to improve the Rev2’s Reverb effect, and drawing from your description, I wonder…
…by layering 2 identical voices with a LFO’ed reverb effect on each, but with one voice being pitch shifted + some delay and slower attack dialled in on its Reverb AMP envelope (courtesy by assigning the Aux Envelope with Env3repeat enabled to the Reverb effect to get that cyclic effect), would this come closer to approaching a “true” shimmer effect? But as you wrote,”The pitch shifted delayed signal should not be mixed into the main mix”. Ah well….

Another, simpler one voice effect, might be try to use LFO4 to modulate LFO3 (where LFO3 is the Reverbs LFO), with LFO4’s cycle timed to give that slightly swelling effect.
Either way, worth shot just to get a new reverb, or two, out of the Rev2.

Thanks james and Razmo.

At the moment (hopefully again later tonight) I am experimenting with this setup:

Rev2 signal (dry or delay included) -->
         Aux1 input MX400 layer 1 -->
                 Hall/Arena Reverb + Pitch shift +1 octave -->
                        Aux2 input MX400 layer 2 -->
                                Hall/Arena Reverb + Chorus (or something else) -->
                                       Aux1 input MX400 layer 1 (now there is a loop)

I only add second layer of the MX400 layer 2 to the mix, layer 1 is zeroed and obviously I add some of the Rev2 dry signal.

Putting it all back into the first Aux1 creates a loop between the two layers of the MX400, but it doesn't swell yet. But it can get very loud if I have the feeds into the loop open too much ;-).

 I need someway of putting another delay in there to create a swell ......

More experimenting to do.

No... the REV2 cannot produce a shimmer FX this way... you would have to be able to route the reverb signal (pitch shifted and delayed) back into the input of the reverb fx.. there is no way to do this, and having a second layer with a pitch shifted sound is not of any use because each layer has it's own separate FX engine... you have no way of routing the FX output of a layer to the input of the FX for the other layer... though this could actually be a fun Feature Request, if the hardware design would allow for it... but still, without a dedicated pitch shift FX, it will not be doable... the REV2 will need an FX engine with at least 3 FX slots per Layer, plus feedback routing options and much more advanced routing options of the FX slots.

For the real shimmer FX, you will simply need an external FX box :) ... besides, I find this ok because I like to put Reverb on my programs as external FX, leaving the FX slots in the REV2 for more modulation style FX and delays.

I was a little disappointed that my REV2 didn't have "dual" effect capability as my OB-6 does. Everything at least needs some reverb in addition to whatever extra effect you may need right?

The fix is easy as you all seem to know already. Add outboard Reverb that's more or less on at all times, and the on board effect can be programmed in to change with each patch as needed.

I'm looking at the less expensive Lexicon MX units. Are there good reasonsto go with the MX 400 vs the MX300?   I see there is also a 400XL model but that appears to only use XLR connections?

I'd like to purchase a unit today!

Well... it more or less does have dual FX ... it's exactly the same as on the OB-6... it has just been split between the two layers, so that they can have individual FX, which in my opinion is a better solution... otherwise the FX would have had to be global for both layers... I know that it allow for more options if both layers had two FX, but they also had to keep cost down I suppose... and it is an advantage that the FX are split to each layer, especially if you use the REV2 as a dual timbral machine, sequencing the two layers separately in multimode... this way you have the FX as a layer-part, and they will be send out from their respective output on the back.

Just hook up an external FX processor, and you can do so much more... :)

And about the difference on MX300 and 400 ... I'd highly advise you to get the MX400 instead of the MX300 and the reason is not very obvious when you read about them... I've had the MX400 and know how the MX300 works.

The main difference is that MX300 is a single FX unit... you can configure it to be either ONE big algorithm, with loads of parameters to change for the algorithm... or you can set it up as TWO small algorithms with a drastically reduced parameter set (just three parameters per algorithm).

The MX400 on the other hand is TWO separate engines each with their own I/O on the back... while this seems to be just two MX300's in the same box, it has one big trick extra up it's sleeve, that is not obvious: The routing can be set to STEREO... in this mode, the processing of both engines can be routed together, so that you can have TWO full algorithms with extended parameter set in tandem, and set them up in different routings... and it all works from the I/O of the A connectors on the back.

You can of course also use the two physical engines separately for a lot of different configurations... but the nice thing about the MX400 is that the algorithms with extended parameter sets can be combined internally so that you can use two algorithms with extended parameters together without having to change cabling configurations on the back for serial/parallel modes etc....

So my advise is: get the MX400... the XL version gives you nothing else but the XLR connections, so unless you really need that, get the one with just TSR plugs...

Yep thanks Razmo, I second that. I got my MX400 second hand for a really nice price and never looked back. At the moment it's main configuration is as a dual affects box adding effects to each Rev2 layer.

Another great aspect of the FX being layer dedicated is that it allow you to create a layer that has the FX as an integral part of the sound engine... if the FX had been global, you would not be able to swap a layer with another without the FX part being compromised...

Actually this is one of the things I find VERY attractive about the REV2 FX section... that the parameters are available in the modulation matrix... this allow me to make interesting modulations of the FX parameters, so as to be part of the sound in itself... the Ringmod will follow the played keys which gives really wonderful timbral possibilities that add organic performance possibilities... the Hipass filter can also be thought of as part of the signal chain simply because it allways follow the layer it was modulated by.

I actually hope that DSI would/could put in more fun FX that would be cool as extra sound sculpting features... Pitch shifter, Ensemble FX, some extra filters (LP and BP), frequency shifter plus other fun FX that would extend the sound potential of the REV2.... an analog synth like this does not have many oscillator timbres compared to the plettora of options on the Prophet 12 for example, and thus can get a bit too narrow in it's tone as an analog synth... extra FX would greatly enhance this, making the REV2 a truly unique machine and set it even more aside from the older P08... especially when the parameters can be modulated from the matrix.
