Specifically, I was trying to think of a way to send random (i.e. sample-and-hold) MIDI CC (e.g. CC 10 for pan) messages out of Modular, each CC being generated as the result of a 'note on' event.

My thinking has got as far as:

Assign the MIDI CC to a control which will be varied by the output of an LFO "synched" to MIDI note-on events. I can't work out a way of getting the LFO to "run for one cycle" every time a note-on event comes in.

The actual situation is that I'm driving Minimax from an arpegiator and I'd like the pan of each note to be random in the stereo field...so I was thinking of driving the pan control for the Minimax's mixer channel from a modular device would, as explained above, would spit out random MIDI CC 10 messages every time a note-on event occurred.

Any ideas?

TIA,

Royston

p.s. I know that in the case of using an apegiator, the note-on events are going to be regular, so in this case I could just synch a modular patch's LFO to the MIDI clock and let it run, but I am interested to see if such a thing can be done just on the basis of the note-on event.

maybe you can use an mvc to collect the gates, and then amplitude modulator. the gate will open the amplitude modulator which will allow the random lfo to send a message to jlk midi foam... You don't have to sync the lfo as you really need random values

You could make a modular with PanMod module that receives data from Note output of MVC after passing them in a couple of Linear Scale modules with high settings....

Cheers for the thoughts.

I did start trying to do this purely inside Modular, until I thought, "how does one pan a stereo signal inside Modular?" which is why I was thinking of controlling the mixer channel's pan control with output from the Modular.

Royston,
if you want to get random pan for each note on, maybe you should look into S/H module in mod3. you can feed it both with lfo or noise generator (for ultimate randomness) and trigger it by gate. if you want to send it outside the modular just hook it to ValMon and assign it to CC

Aha...ingenious! :smile:

Cheers Michu...that makes sense.

Had a thought (the second this year!)

If the S&H module were triggered by gate, then the gate would be open as long as the note lasted, no? This could cause multiple MIDI CC events to be generated, when I only want one.

I was monkeying around with note transformation in the logical editor yesterday - that's one way of getting the result I was after; copy the MIDI event and transform the notes into whatever CC you want with random values.

Then you can use MIDI to Trigger between the MIDI input and the S&H instead of using MVC's gate output... Trigger is a momentary event.
