Here's how to create a 909 style kick with a lot of tweak-ability.
For this we will be using just one oscillator
Start by pushing encoder OSC WAVE > 1/26 VCO Shape set it to 0 (the higher you set it the rougher it gets
Now make sure that no other oscillators are active by making sure OSC Wave pages 3/26 - 6/26 on the other oscillators are set to zero too.
From here, check the envelope in the VCA > EG Balance > set 1/8 > Att: 2 dcy 94 Stn 165 rls 36 - this can be adjusted later, but the important part is to set the release to above 10 (or 20) to avoid clicks.
Now push the OSC Detune encoder in the VCO section > 1/ 4 VCO fine and 4/4 VCO0 Pitch should be set to zero > set 3/4 key scale to 12 > set 2/4 course to -24 > while on this page press the encoder below OSC 1 > Pitch envelope preset should be set to zero > press the encoder below OSC 1 > VCO1 Pitch set: stpt : 33, time: 25, time: 0, endp: 0
Try hitting some notes, somewhere on your keyboard you should have a nice and phat classic 909 style kick. Give it a save.
Now for some tweaking.....
VCO 1/4 stpt parameters 25 - 60 = adds more chirp, like a trance or hard techno kick.
VCO 1/4 Time parameters 25 - 50 = makes the tone more apparent
VCO Course parameter -24 = +/- climbing tone vs flat
VCA EG balance attack parameter 0-30 = higher number means less click on the front (smoother)
VCA EG balance Release parameter 20-80 = higher number is more like an 808
VCO WAVE shape 0-? = the higher the number, the more industrial sounding
wait there's more...remember the signal goes right to the bus?
Try routing it to the LP for that extra resonating thunk, the MM? The FB?
Double the oscillators...vary the waveforms...you get the idea.
Can't find that perfect kick for your track? Put it on an unused trigger group/oscillator (if there are any) and tune it perfectly...or sample the hell out of various kicks and put them on an SD card.
Damn the spectralis rules!
