Watched your video earlier and I really like those patches! Please give some examples of what "subtle movement over time" you program.
For me, what makes a patch sound 'good' is that once it hits the sustain of the envelope, is that it's not static...our ears get bored quite easily and while its easy just to grab a knob and turn it in real time, I find it best to keep the movement going when it hits this stage, so program it in. The wheel is good, but it does mean you have to take a hand away, so I put a lot of the duties i'd normally do for the Mod wheel, assigned to After touch. Of course, this isn't always the best for the sound, so I may have a positive increase on the filter with the wheel, but a negative on the Aftertouch...so when playing, adjust both of them simultaneously...often competing with each other or complimenting.
The LFO is the best tool though, pretty obvious really but i'll dial in just a small amount of initial LFO to affect the Filter, but on a very slow setting. Unfortunately, I do find the wave shapes for the LFO (other than Sine) to be too clicky for Filter or Amp and would be great if they could implement a SLEW parameter to take the edges of the waves. That said, as you can use the 2nd Oscillator as a LFO and set it to Triangle, hit Sync and then you can use that to modulate Oscillator 1 and use the LFO at a different rate.
I've just made another 20+ patches for it, that experiments more with this...I'm still learning the capabilities of the Synth myself and using Bandpass more and other things. I'll be selling the patches, might wait until I do a full Bank...won't over charge for them, but I might do a video of things i've found good for programming the Synth.
