Please could someone at Moog or a fellow forum help me with the below Moog Sub Phatty tech issues, please?
When I power up the Sub Phatty, and go into Active Panel, does the ladder
filter by default go to a 1 pole filter?
Also, I am a synth novice, have been trying to work things out for myself,
but am getting stuck on this one: I want to connect Korg Volca Beats cv out
to Sub Phatty cv in: Is this safe? I want to lock the beating pulse of a Sub
Phatty looped envelop to the Volva beat drum pulse..
Can I also lock the Sub Phatty LFO pulse to Volca beats?..Will this be best
via Mid connections between Sub and Volca? Is connecting two different
devices safe??Will it be possible to do this?? I think I am getting the
connection process wrong, please could you help?
I don’t own any Sub myself but use a friend’s one on a regular basis. I think the panel mode has its own setting, which might contain the filter configuration. I guess if you change the pole number while in panel mode, it will remain as this as long as you don’t set it otherwise while in panel mode.
Pluging a “CV out” to a “CV in” makes sense technically… but you may find out it doesn’t make sense musically. What is that Volca’s CV out? Pitch? Filter cutoff frequency? And what is the Sub’s CV in you’re taking about? I’m sure you’re starting to undestand In all cases, I think you don’t risk to damage anything.
Finally, MIDI is a safe way to connect two devices, albeit different ones. You will be able to sync the Sub’s LFO on the Volca’s clock, I guess.
The Sub Phatty’a C.V inputs are: Pitch CV, Filter CV, Vol C.V and KB Gate.
I go to plug in the C.V out of the Volca ( this C.V. out I believe is just a clocked Pulse) and I then have been experimenting with plugging this out put into the KB Gate of the Sub Phatty. Before I turn the volume up on both the Volca and Sub Phatty, I change the tempo of the Volca, and the Lfo LED on the Sub Phatty does now blink in time with the Volca Beats.The thing is, when the volume is turned up on both machines, it still feel as though the LFO of the Sub Phatty is not beating in time with the tempo of the Volca, so I have no idea what I am still doing wrong…Blimey, that was long winded, sorry about that.
The Clock CV out sends clock ticks, that is impulses.
Amongst the CV inputs of the Sub, you have three continuous controls and one that accepts impulses: Kb gate. Each time it recevies an impulse, it acts just as if you had pressed a key, that is it triggers the envelopes… except when you press a key, you actually give several pieces of information to the synth: a gate signal for envelope triggering, a pitch signal for the note to play, and/or other things like velocity.
Connecting (only) the Volca’s clock out to the Sub’s KB gate in will trigger notes on a regular basis, the note being the last one you played on the keyboard. You can try it
Now, if you want to sync the Sub’s LFO on the Volca’s tempo, I think you’ll have to use MIDI. On a sidenote, when you di that, the FLO rate knob sets the LFO rate in a different way: the speed is a subdivision of the input tempo. Consequently, it always stays synced, but with different feels.
Thanks for your reply, and sorry about the late reply to you.
Thanks for the information about cv signals/KB gate and Midi connecting to the Volcas.
I have tried the Volca out to kb in and have managed to Midi Sub Phatty’s Lfo to the tempo of the Volca…all is working fine now.
I have also tried experimenting with looping the Sub Phatty’s envelope ADSR and amp ADSR, and when combined with the LFO, the impression of x3 LFOs is given..Three rhythmic pulses, plus the pulse of the Volva beats.
All working well now thanks: I have MIDI out of Sub Phatty to MIDI in on Volca beats, and when I change the tempo on the Volca the LFO follows the tempo change.The looped Sub Phatty envelope and Amp compliment the pulse created by the Volca Beats and Sub Phatty LFO.
Thanks for your help on this once again.
All I have to now do is work out why the octave lights don’t stop blinking when I tune the 2 Sub Phatty Oscilators via the hidden functions…The only way I have been ale to stop the Octave lights blinking is to switch the Sub Phatty off, then on..
If your Volca only receives MIDI but does not transmit MIDI, it certainly won’t send any tempo signal. I can’t see how the Sub Phatty can sync to the Volca when you change the Volca tempo.
This is odd, I am convinced I set the Volca Midi option to ‘external’, I connect MIDI out from the Phatty to MIDI in of the Volca.
Next I set a drum pattern going and adjust the temp knob on the Volca, and I am sure there is some movement from the LFO on the Phatty.
I will try again, maybe I am hearing things that are just not there..
Looking at things another way, there is no 'tempo knob ’ on the Phatty so to speak, and I have tried changing the LFO clock on the Phatty when the Volca is playing, but the tempo stays the same.
I will report back should I try again and hear any further changes..
