Okay, I finally got the Launch Codes.
It seems to be doing pretty much what I hoped it would do! In-sync triggering of loopers, manual triggering of stuff, etc.
Here's a short video that's really crappy but probably gets across the way I'm going to use the Launch Codes. Sorry for the image quality.
Here's a few notes on what I'm doing:
Antimatter Launch Codes controlling the ER-301.
Channel 1 of Launch Codes triggers a Basimilus Iteritas Alter.
Channel 2 of Launch Codes triggers Reset and Punch of a looper on ER-301's channel 1.
Channel 3 of Launch Codes triggers a sample player on ER-301's channel 2. (this sample player shares buffers with the looper on ER-301's channel 1.)
Channel 4 of Launch Codes sends triggers to a Shapeshifter, under 1v/oct control from elsewhere.
First I play a drum pattern on the BIA. Then I unmute channel 2 of Launch Codes, which makes the looper record what I just tapped in. After this, I just mute channel 2 of Launch Codes (so that the loop doesn't get overwritten, let channel 3 of Launch Codes trigger the newly recorded loop.
Then I re-use the BIA, changing some settings and tapping a new rhythm on Launch Codes' channel 1.
Last up, I trigger some dubby chords on the Shapeshifter using Launch Codes' channel 4.
Sorry again for the production values, hope you get the idea!
