Not really played around with chords and Euclidean mode much. But yeah, from memory, when you’re in Euclidean mode, if you hold down the main encoder the pads light up like a piano keyboard.You can play a chord in from there using the pads and transpose it up and down using the <>. If you’ve got a midi keyboard connected then you can bang a chord or a note in on that - although i never tried it.
I don’t think you can programme a different chord on each Euclidean step though. (There are plenty of super -users on here that I’m sure will correct me if that’s wrong!)… It just loops round sounding chords on each euclid step depending on the last input. But if you’re happy with your pattern you can always bounce it out and then turn the steps into specific chords from there (although of course, you won’t be able to change up your euclid pattern, which is where the fun lies, right?)
Alternatively you could make up patterns with different euclid steps and lengths and different chords, stick the patterns in different sequences and then chain them together. Or just jam it out with a tonne of different patterns you like and record the midi output. (Set the pattern delay in settings to BEAT to get the best out of this). I find this much easier than using the encoders on the fly to tweak the euclid controls and trying to remember which combo of steps, length, phase etc I liked best.
Last time I messed around with it I used a combination of Master Track Transpose to move the euclid note around and harmoniser FX on the euclid note output to sound the chord. Doing this you can put a ‘straight’ chord sequence/riff down in your Master Transpose track, like 16, 32, 64 steps or whatever, but when you slave the euclid track to it, the “chord” will sound out as per the euclid settings so you get rolling and evolving poly rhythms that are melodically related to the rest of your track. (If you’re track is generally in 4,8,16 bar phrases of course.
Bit of chance FX on the euclid track, some swing, CC LFOs for your synth, touch of delay on your audio output to give it a bit of a regular pulse and you’re away.
