Negative EG filter mod feature request

Negative EG filter mod feature request
« on: October 24, 2021, 01:31:58 PM »
The prophet-5/10 reissues are amazing. I love mine and I love the new OS with split/stack.

Even though it is a pretty faithful reissue, I think it would be great to have the option of a negative filter envelope.

Is this possible since the envelopes are software?

Maybe the user could toggle between + and - by a button combo, something like preset + keyboard tracking button?

Just spitballing here, but I think it'd be great.

Still think this would be great!

Yeah, if it´s possible, why not   ???
I remember my old KORG Trident had
that feature back in -82   8)

An "EG Sensitivity" knob, at 12 o'clock "0", full
counter clockwise "-5 ", full clockwise "+5".
Got some useful sounds out of it  ::)

I would like to see that being implemented as well.

You have to remember what the P-5 is about.  Negative EG's are great and are on the other Prophets.  However, part of the art of sound design are the limitations placed on you by the instrument.  Dave Smith did about all he could do on a Rev. 4 and keep it true to the P-5 heritage.  IMO, he did a masterful job.  The feature set of the P-5 will keep the sound designer moving he direction of the original P-5.

I do see your point. These synths are about simple controls and straight to the point editing/playing, adding too much complexity would steer it away from the desired simplicity.

That being said, adding bi-timbrality to the P-10 doesn't fit that philosophy, but the addition of it is absolutely fantastic with the reissue.

The bi-timbral option is also more complex than how I suggest a negative filter EG option could be implemented. You'd just hold preset and press the filter keytracking button to switch between positive or negative filter EG.

Adding this feature would be completely non-invasive to the authenticity of the original.

It's strange that a lot of Prophet 5/10 reissue owners seem to be requesting a lot of features that are already available on the Prophet 6 and Prophet REV 2. I saw someone on this forum asking for an arpeggiator or sequencer to be implemented....at some point you either want an old school instrument and can accepted it for what it is or you have to move on.

Arp and sequencer request for P5/10 is way over the top, though negative EG feature request as I suggest isn't at all. IMO it totally lends itself to having one since the envelopes are software.

out of curiosity, what kind of sounds can you do with a negative EG? also, negative time?? I can grasp the concept of a negative level though, or is it that which you’re actually referring to?

It's the same as the normal filter EG on the P5/10 but the voltage is inverted.

So instead of the filter opening up on key press, it closes on key press. The timing of the envelope mod amount is the same as whatever you set the filter ADSR to.

Negative envelopes have been around since the 70's. It's a simple feature that opens up much more sonic possibility.

Where I respectfully disagree is that the original P-10 was bi-timbral (two manual version).  https://synthmuseum.com/sequ/seqpro1001.html

Not really ....   The ORIGINAL P-10 was one keybed just like the new Rev 4 .
The two keybed version was / is "duo timbral" witch IMO isn´t "Poly"   ::)

Cheers !

The two keyboard version had a mode where you could stack both sounds on the same keybed. It also had a cool mode which alternated between the two engines with each note pressed.

How that isn't "poly" I have no idea.

I didn't know that, my mistake. Though I still think adding a negative EG mod is a great idea since it would be completely non-invasive to its original UI. Anybody who wanted pure original authenticity could still use it as is.

 I'm not a programmer, but I imagine it wouldn't be too difficult to add, and it would add a lot to an already great synth.
