True. Though there are synths, I think for example the DW 8000, which allow you to keep playing without the forced note off, so while you're holding down the keys, you can actually switch the patch without interruption. Works great for patches with a long release or even with no decay like an organ.

I know this from most synths, that the sound is simply cut off when changing presets.
With a few synths, the original sound still fades out despite the preset change.
But no matter, with the REV2 it is the way it is.

This happens with the P6, P08, OB6, PX too

Haven’t noticed this before , and it’s not an issue in my Pro 3. However I’m getting usb squeal at around 4khz. It’s only noticeable when I have a maximiser on a mix to about -9 lufs. I can notch most of it out , but I’d rather not.
I’ve tried a usb isolator that cuts any power, but it’s not passing the data for some reason. Tried powered usb hubs , straight into my Mac Mini , my last option would be to use din , anybody else had this ?

You should really ask this in the Pro 3 section.  Why would you ask it in the Prophet 5 Prophet 10 section?  Usually people here don't have Pro 3s.  just sayin.

oh you have the prophet 5 prophet 10?  No never had that problem on my Prophet 10.  I just had the problem that a VST AMPIRE was causing some problems in my signal coming from Reface DX.  It had the cabinet emulator on it, and was making a buzzing and high pitched sound because of that.  You probably have something similar.  Have you isolated the problems and if so what audio relaying programs did you isolate them in?  Did you try isolating the problem with a different maximizer?  Is that a VST Maximizer?  Does it also happen when you are not on battery or on battery for your little laptop?  I find that the problem of hum and buzz can be different depending on the interface or laptop being plugged. 

It is really bad to use a Maximizer.  I was glad to get rid of it.  Other plugins I was able to get rid of after I discovered that noise was made by the AMPIRE VST included, Waves AR Mastering plugin, 2 different gates, Maximizer by AIR, Izotope RX7.  It was a total relief to get rid of these plugins.  A complete load off.  The Maximizer in particular was a real problem cause it lowers the volume of some of the instruments in the mix when some loudness from one instrument comes along.  Not just that, but maximized music is like an illness.  Grunge music of the 90s and 00s comes to mind.

Hi, I figure this would be as good as a place as any to post since Dave Smith is considered the father of MIDI.

Ive made a thing I'm calling MIDI Goblin.


It's a small, device with a little oled screen that allows users to save patches for user defined devices....meaning it can save patches for any synth that can transmit midi cc/nrpn messeges. Kind of like a really flexable hardware patch librarian. 

You can also use it to name patches saved on your patch banks, then load them by name in any order....I think this is one of the most important features and intentionally made a demonstration video of this feature using an OB-6(seemed appropriate)

It also has an arpeggiator function for synths that lack arpeggiators but can transmit midi note on/off messeges.

 a chord generator that automatically plays major or minor chords and if you have extra voices, you can play over top of the chord. kind of fun!

There's also a MIDI CC lfo, that can emulate multiple waveforms (though i think the code for the sin and tri waves needs to be re-worked...they sound very similar)

You can remap MIDI CC messeges. This could be really handy for old midi controllers...Also it allows you to remap your synths midi cc values so you can program one synth with another (and the MIDI Goblin can save the patch data as well)

It also has a scale thinger... its really fun sounding. press a note, a major or minor chord is played as an arpeggio

And it has a 32 step sequencer...suprisingly it was the easiest thing to program.

The MIDI Goblin can be programmed using the Arduino IDE so if you want to use it for something entirely different its a pretty useful prototyping tool and I'm going to make the source code openly available too.

I think a lot of the features on the software side are handy. It does some stuff for assembling NRPN messages while filtering out message fragments that I'm pretty proud of.

I like the idea of something that returns an arp based off the chord or notes I play on the Prophet.  How much is one of these costing?  Not sure it will be useful but that is one thing I sort of could use, an Arpeggiator that takes MIDI in, and translates it to an arpeggio, then sends that arpeggio back out to something further along.  Do you know this has always been impossible to achieve? 

For instance, take the simple VST RandArp, from Code 42 ( https://codefn42.com/randarp/index.html ).  This is a great little Arpeggiator to put on a track in a program like Live Professor II in front of a VSTi, because it will take notes sent into the chain from a midi device and turn them into an arpeggio that plays the VSTi.  However, when you try to get an outputted ARPEGGIO (MIDI out) from the chain, that is being created by the VST, it is impossible to get one sent thru the MIDI out and sent to a further chain or a program with transport to record that MIDI created by the RandARP.  Believe me I have tried.  Though it was a couple years ago.  As far as that time, there was never any way to record the MIDI from the RANDARP VST. 

I'm not sure I use the 5 Pin MIDI in/out ports from the prophet actually or thru.  I used to use them but maybe not anymore.  Might just be a useful device.
