I think I've worked it out, and you don't need the Environment. If anyone else is interested: 1. Use Audio MIDI Setup App to set up a new IAC Bus 1 (https://sites.google.com/site/mfalab/mac-stuff/how-to-use-the-iac-driver) 2. In Logic, Instrument track 1: Input is Utility > External Instrument, MIDI destination IAC Bus 1, outputting to all MIDI channels. Its MIDI Channel is 1. My keyboard controller is set to output on Channel 1. 3. Instrument track 1 has MIDI Scripter FX which separates incoming note data into different midi channels (2-16, not 1, which would create a feedback loop). 4. Other tracks have MIDI channels 2-16 and are record-armed. 5. Select/Arm track 1 In my understanding, if you want to record what you play, you're effectively limited to 15 MIDI tracks. If you don't, you can direct different IAC Busses / physical instruments directly to different tracks/groups. Is this correct?

My query is similar to this. I'm trying to write a script that analyses and parses MIDI data out to different instruments. - I play notes that come in to MIDI channel 1, which come into a track where there is a MIDI Scriptor. (I've got a separate controller on channel 16.) - The Scriptor separates the notes into different MIDI channels - Then I want to route that multi-channel MIDI data across multiple Software Instrument tracks - And I also want to be able to use MIDI controllers / iPad remote to configure those tracks (e.g. there might be three instruments picking up MIDI channel 4 but I might want to turn one of them on/off so it doesn't play How do I do this? It's a shame you can't have MIDI Scriptors on summing tracks or in the Environment. I'm fine with the javascript but am a novice at Logic Environment and IAC Busses. Thanks for any help!

I guess you might have five hi-hat samples mapped to different note values -- e.g. closed A4, half-closed A#4, half-open B4, open C5, foot-down C#5. Then as you lift your foot off the pedal (value goes from 127 to 0) when you press some key on the keyboard (e.g. D5) the sample that plays back varies from the A4 - C5 key. Ideally, when you put your foot down after the B4 or C5 samples, you'd get C#5. Or, in a more simple scenario, you have just two samples -- open and closed. If a non-continuous switch is pressed down, when you press a key (D5) you get the closed sample; when the switch is up, you get the open sample. It's all getting a bit complicated...

Yes, for an EXS kit. I guess if I can't use the continuous message sustain pedal for a kick drum, it would be good to use it for the hi-hat -- i.e. mapping samples from fully closed-half open-fully open. Doable? Thanks for your help!

Does anyone know how I can use standard foot pedals to act as drum pedals, to trigger MIDI drum notes? I want to use a continuous damper pedal (sending 0-124 down CC64) to act as a velocity-sensitive kick drum trigger -- i.e. converting the speed with which I put my foot down from 0 to 124 (it doesn't seem to get to 127 for some reason) determining the note velocity for some specified note on message. On the easier side (?) I'd then like to use a standard sustain pedal (0/127 down CC67) to control hi-hat open/closed. Can anyone help? Thanks, Ben
