I was told the APC buttons send a 'note on' message on button-press and a 'note off' on button-release. I'm trying to turn my APC's mute buttons from toggles into momentary buttons for my performance template. I read what little there is of a manual, I did a search on google, and on this board which didn't yield any help. I am as well curious about similar software for MIDI manipulation, preferably released Open Source.Īnother idea would be to solve this with a nice Max4Live device.Hey Ya'll so Im trying to the a simple task and I cannot seem to figure out this app MIDIpipe. If you find a way to code this all into one script or even solve the message manipulation without AppleScript, just using a combination of MidiPipe’s other modules, please leave a comment, I would love to here! Also MidiPipe is a rather dated piece of software and is not in active development anymore. I even sometimes use it for live finger drumming. So far it doesn’t seem all this introduces latency that delays the drum hits noticeably. In MidiPipe set the two “Midi Out” modules to the port your Volca is connected to.

In your DAW you now have to send the output of the MIDI track you use for triggering the Volca to “Midi Pipe Input1”. set channel to (( item 1 of message ) mod 16 ) # 144 is Note-On on channel 1 set first_byte to ( channel + 144 ) set note_no to ( item cnt of note_list ) set note_val to ( item 3 of message ) #display dialog 'CC to note -> ch:' & channel + 1 & ¬ ' note_no:' & note_no & ' CC_no:' & CC_no & ' cnt:' & cnt set ( item 1 of message ) to first_byte set ( item 2 of message ) to note_no set ( item 3 of message ) to note_val # we found the CC_no and translated to note, nothing else to do exit repeat end if set cnt to ( cnt + 1 ) end repeat return message end runmeĭownload my MidiPipe config file and if you not already have, MidiPipe. # translate note to CC # comment out for debugging from AppleScript editor #runme( set cnt to 1 repeat with CC_no in CC_list #display dialog (item 2 of message) if (( item 1 of message ) ≥ 176 and ( item 2 of message ) is ( CC_no as integer )) then # returns 0 for channel 1, 1 for channel 2, etc. The second AppleScript Trigger translates the MIDI CC messages back to Note messages and sets their velocity correspondingly:Īnother Alist, here we should see a MIDI CC message followed by a MIDI Note for each drum triggered:Īnd finally everything is sent out to the same MIDI port as above: MIDI CC messages are sent to Midi Out port as well as passed through to the next module: The first AppleScript Trigger translates the Note messages to MIDI CC messages (full code is below pics): The AList modules are for debugging, they show how the MIDI messages look like at the current point in the pipe: We only want to manipulate MIDI Note and Control Change messages. The settings of the modules in detail, obviously this is the input: You can see that I use two AppleScript Triggers and also two MIDI outs: The right half of MidiPipe’s window shows the modules the messages are flowing through. I couldn’t find a way to code this all into one AppleScript so my solution looks like this. now that the volume is set, send note to output too.

generate new CC message with correponding number and value (e.g.

Hence I decided to use MidiPipe’s “AppleScript Trigger” module and manipulate the messages myself. One of the main reasons was the lack of being able to generate a new message according to values I got from another message.

There are quite a lot of types of modules that are able to translate, manipulate or even remove messages but they all didn’t manage to solve my problem. For more details click the link above to MidiPipe’s homepage. A MIDI messages flows through one module after the other from top to bottom until it reaches an output which in my case would be the MIDI port the Volca is connected to. MidiPipe basically works like this: You put togehter an input, a couple of modules and an ouptut. The values of these two types of MIDI messages generally range from 0 to 127, so this should work out without any complicated maths magic. My next idea was to use the Freeware MIDI manipulation software MidiPipe and just translate each notes velocity value to a newly generated CC message. +-+ +-+ +-+ +-+Īlright, drawing velocity with an automation line ranges in the top 5 of the most tedious things I have ever done in Ableton Live so let’s gently call this approach rather unsatisfying and let it go…and yes, instead of drawing this beautiful piece of ASCII-art, I just could have presented a screenshot of my automation line in Live but I am not willing to search for it in my projects and certainly won’t draw a new one -)
