I did notice in the recorded MIDI item there is a 'PC' where I grabbed the cymbal (attached). I think it's great REAPER has all these great tools for problems like this. I was thrilled to see it working and thought I would share it here. It converts the Poly aftertouch to a Program Change. The fix is to add MIDI Converter 3 on the Input FX (before EZDrummer) and set the sliders like in the attached image. (This is after it is converted from a9 31 7F to c9 00 00). See in attached examiner and logger image. This is on note C#2 crash on the Nitro and in EZDrummer. I found the Nitro module choke/grab sends poly aftertouch (a9 31 7F). I don't know exactly what Program Change it's using in the MIDI Converter, but it works great. I was playing around with it again today using VSTi MIDI Converter 3, JS MIDI Examiner, and JS MIDI Logger, and happened onto this fix. I would have to restart Reaper to get it unstuck. Problem was when I did a crash cymbal choke (grab) on the Alesis Nitro drum kit, the choke would get stuck in EzDrummer. (The solution in this post didn't work out). UPDATE 2: Skip this and go to next 2 post. I finally gave up and bought Addictive Drums (which cymbal chokes work fine in it). I searched all over the web for months and never could find and answer. Thanks for all the great info! I ran across a fix today and hope this may help someone. I've been reading the Reaper forums for years. My chain would be CODE 61 Midi Out -> Midi Thru box (to split the signal) -> Midi Filter box -> MPC Live Midi In.First post here. Or at least filters out the information on all other channels. So I am looking for some small piece of hardware, that I can place before the MPC, that filters out the rest of the information, and only leaves the one channel that is meant for the MPC left. The problem is that the MPC's Midi In is Omni-mode only, so it keeps reacting to what is happening on the other midi channels. I am going to split the Code 61 into three different zones, each with their own midi channel, and send it out through the only 5-pin Midi Out of the keyboard. I am building a setup where i am controlling a Yamaha Reface CP, an MPC Live and a Roland VT-4 via midi - all from an M-Audio Code 61. Hi! I am looking for some small piece of hardware that will let only specific midi channels through, and filter out the rest.
