problem with midi after touch.

October 1, 2011 | 4:29 pm

I’m using a channel after touch thing (it’s a patch that produces that along side a pitch bend).
& after experiencing a recurrent crash I noticed that that i’m getting a shit load of after touch messages (about 1000 a second to be exact, but this wasn’t really a surprise because I timed it that way to match the pitch bend)
so my conclusion was that I obviously had no idea how midi after touch works and playing the guessing just got me crashing.
is it like velocity? one message per note? or did i just over do with 1k per sec?

I remember some of you guys explained the 14bit pitch bend to me in minutes. so I know you can help me with this.
thanks in advance

The purpose of aftertouch is to change sound parameters like volume or vibrato while playing a note.
So it’s normal to have multiple messages per note. But a rate of 1k per sec is usually not needed.

Aftertouch is designed to give you a ‘touch feel’ with a continuous controller, for example the FC of a filter with a continuous more of less hard press of a note. So I would also say that 1000 a second is overkill.
