AUM same midi message with every note
Hi everyone
Like the title says I’m looking for a way to midi map all keyboard notes to the same parameter of an effect.
For better understanding: it’s an lfo with a start button parameter that I want to trigger each time I play a note. So that the lfo becomes more like an envelope.
I can easily map it to a single note and it works fine. As long as I press the note the lfo is going. But I don’t seem to find a way to map all the notes to the Start parameter.
I also had the thought there might be a midi facilitator app that can map several values to a single one.
What are your ideas guys?

You will need to use an intermediary app/plugin. The free midi scripting streambyter plugin can do it.
Use StreamByter to convert note on and note off to a CC:
Using CC #6 here; could be any. Numbers are hexadecimal, so be careful! This maps any Note On to CC 6, value 127 (hex 7F); and any Note Off to value 0. Copy/paste this text into StreamByter and Install Rules. If you do this in your AUM session, then save the session, this code will be saved with the session state.
Route your notes to StreamByter; StreamByter output to MIDI Control in AUM. Then map the CC to your control.
Playing this polyphonically will be confused, since any Note Off will stop the LFO until another Note On arrives. It would be a bit more complicated (but not difficult) to sustain the LFO as long as any notes are playing.
Wow thanks. I will try that.
I already thought that polyphony will get rather complex. My first thought was using a mathematical sum: every note has the mathematical value of 1 and every note added will add a +1. than you would set the lfo off value to 0 and lfo on value from 1-127. I don’t have a clue if that’s in anyway possible but that was my first thought. Legato envelope. I thought about real polyphony and I think it is impossible since you would have to have one instance of the modulated parameter per note. Or am I forgetting something here?
When playing polyphonically, do you want each new note to retrigger regardless f whether other notes are still playing?
Do you want note offs to have an effect or do you only care about the note on events?
Exactly. StreamByter can easily use a counter to run the LFO as long as any notes are playing. It requires an actual script, not just the simple remapping rules I provided.
True polyphony, with an LFO per note, would require an LFO inside the synth, that can be synced with the note start. I believe some synths have that.
