Help w/ Midi Device for Buchla Easel Command
Hello there! I'm a complete beginner and any help is very much appreciated.
I'm attempting to create a midi device specific to the Buchla Easel Command. The device would simply trigger a midi note of a specified value (i.e. Midi Note #6) every time any other note value greater than midi note #24 is received.
The reason for this is that the Buchla Easel Command requires a note on/off sent to specified note values to trigger it's various patchable components-- envelope generator, pulser, and sequencer-- So if I simply send a melodic midi stream to the instrument it will play continuously with no gating or performance dynamics, unless I also trigger the envelope at the exact same time as each midi note in the melodic stream. For example, if I want to trigger the envelope at the same time as a pitch value is sent to the synth- I'll need to duplicate all midi notes in my sequence then transpose the duplicated notes all to the specific note value which triggers the envelope (which happens to be midi note #6).
So far I've been banging my head against the wall in the following way:
Ideally, I'll have a device that lets me select which "trigger" note I'd like to automatically generate (be it the envelope, pulser, random voltage, etc) via a toggle.
Thank you for any advice!
This patch successfully triggers the desired note # 6This patch actually does nothing apart from sending any incoming midi event and then the value "6" (without velocity) to [midiout] ;-)
I am not sure to understand exactly what your detailed expectations are, but, focusing on the following:

Hi Sébastien, thank you for the response!
Perhaps I totally botched it but, when I attempt to run the patch you've suggested in Max 4 Live, no midi passes through. Because I'm in a M4L 'Midi Effect' patcher, I'm using [midiin] and [midiout] rather than use [notein] and [noteout] (although I attempted the patch with [notein] and [noteout] as well).
To be clearer on my intention:
I'd like MIDI note #6 to automatically trigger anytime any other note is manually triggered. In the example below, the melodic content intended to play on the Easel Command is outlined in a red box. The notes outlined in the yellow box occur at exactly the same time as the melodic notes, but only occur on midi note # 6- to trigger the envelope generator of the Easel Command:
Ideally, the desired 'trigger note' would only fire if notes greater than midi note # 24 were received- only because the Easel Command does not receive pitch information below midi note # 25.
I hope I'm explaining this clearly and thank you for the help!
Okay, then. You send a chord of 2 notes : one being the actual played note, and the second being always an F#-2, whatever the first note number is (but providing it is >=25). You may add [makenote], as well, should you want the F#-2 to have its own duration, or remove [stripnote] should you need it to be the same length as the triggering note :
Generally speaking, the fastest way for you to find your own solutions is to 1. read/understand the help pages of these different objects (in this thread only, we already mention a lot of the very important/basic-toolbox ones : [route], [trigger], [split], [notein/out] [midiin/out] ...) 2. test them.
Thank you very much for the assistance, it is very appreciated! I'll continue to fiddle with it
Hello Sébastien,
I've created the desired midi device! I wound up using [midiselect] -> [unjoin]->(4)[trigger x] objects with desired midi note numbers for x-> [switch]->[flush]-> [join]->[midiformat]->[midiout]
The [switch] is switched via a [radiogroup] to specify the desired [trigger x], which in turn automatically triggers the midi note value each time a manual midi note is triggered.
Thanks!
