Want to pause on this takeaway (likely a simplification but still significant): LFO -> amp = tremolo LFO -> filter = wobble LFO -> pitch = siren LFO -> pulse width for pulse width modulation.

So I replied about the nick batt joke and I'm now realizing I didn't make it through the whole video. When you mention syncing LFO delay to tempo, do you know if the numbers correspond to any specific units of time? Or is it mostly by ear in relation to incoming midi clock (if any)? Anyway, these videos are truly opening up FM synthesis to me...if slowly because so much of it is counterintuitive lol. But thank you so much for the videos!
@OscillatorSink
@OscillatorSink 2 года назад
The LFO numbers do mean something, but it's just Hz rather than being clocked to midi. The trick is to get something close enough and then turn on LFO Key Sync in the global operator settings so it resets with each key press, that way it never gets too far away from sync.
@naedyr
@naedyr 5 лет назад
With the sample and hold LFO, to avoid the glitches, you said there are certain things you might want to turn down. What are they?
@OscillatorSink
@OscillatorSink 5 лет назад
Primarily keeping the Amp Mod Sense (AMS) and overall level on the operators you're modulating down. But essentially this glitchiness shouldn't exist at all and appears to be a bug with the Volca's firmware.

Ok for some reason when I want lfo to modulate amp on operators, it doesnt do anything. I set all "AMS" parameter on all operator to 3 and I dont hear any difference even though depth on lfo is all the way up and "LAMd" parameter all the way up as well. Im getting frustrated :/
@OscillatorSink
@OscillatorSink 5 лет назад
The "LFO Pdepth" on the front panel is just for pitch, so you shouldn't need to alter that. I would start with just one operator to trouble shoot. Turn off all the operators but 1 and set the algorithm to 32 so you are sure you're hearing that operator. Set that operator's level to 75, the AMS to full In the all operators settings, set the LAMd to full (double check it's the LAMd that you're changing and not LFOd). And set the LFOW to 0. Do you hear any tremolo now?

thanks for going above and beyond - much appreciated! i didn't really want to get into this much detail for the fm but i fear i must to get the most out of the beast. i like the way the earlier vids simplify things and start out with only 2 operators, a carrier and a modulator so you can actually clearly hear the changes. do i simply turn off operators 3-6? which algorithm is best to use, some have a 'looped' modulator 2? my biggest gripe with the fm is the difficulty creating/recording a track or layering different patterns over each other. i much prefer the volca bass way of doing things, with 3 oscillators/voices that can be layered over each other and a step mode. right now i'm forced to record a loop from fm into audacity and then create a new pattern/loop with a new program and algorithm etc and record that over the 1st loop. is there an easier way? thanks again.
@OscillatorSink
@OscillatorSink 4 года назад
If you're just playing with two operators (a great strategy for learning!), use algorithm 2. Op 1 is your carrier, Op 2 is your modulator which also has Feedback to play with as well (increasing the feedback will increase the richness and raspiness of the sound generally). What you're describing is the only way really - you only have one timbre to work with at a time I'm afraid.

@@OscillatorSink ya, i finally clued into that so i just saved the whole patch, e piano, with the algorithm editing for 2 operators (1 and 2). went through episode 2 again and tweaked along with you and didn't quite hear the changes as clearly as in your tutorial (maybe it's the e piano sound carrier?) but i was able to eliminate some 'nasty' treble' overtones with the 'FreC/F' settings. didn't hear much difference with 'Fdbk' changes also (using algo 2 with only 1 and 2 enabled with feedback loop on the mod, 2) thanks again, much appreciated. plan to do the same thing with the envelopes episode today. your info is a much needed addendum to the rather thin FM manual.

what parameter does the modulators wave form modulate in the carrier? thanks
@OscillatorSink
@OscillatorSink 5 лет назад
The level - same as with the Modulator, which gives you a kind of tremolo sound.
@ajdooom
@ajdooom 3 года назад
I always wondered why the modulator is on the left and the carrier is on the right. It seems obvious to have the carrier first, then think of the modulator affecting that. Especially since the carrier is operator 1? Is this a Japanese right to left thing?
@OscillatorSink
@OscillatorSink 3 года назад
I think it's more that the modulator flows into the carrier - if you think about the way the algorithm is laid out, that's modulators at the top as well, again, flowing down into the carriers. Modulator first is a more natural way of reading it for me anyway.

Thanks again. I was wondering why the LFOP knob didn't work on certain preset patches. Now I know. Currently experimenting with chord-spread/pseudo-arpeggio on algorithm 32 (as explained in ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oceFFISc11A.html). I like the LFO-delay setting very much. Keep up the good work as it's really appreciated here.

Is it possible to 'export' (save) a patch to pc ?
@OscillatorSink
@OscillatorSink 7 лет назад
+Holy Diver short answer: no. Better, longer answer: yes, but you have to mod your unit to have a midi out port. The capability is actually present in the unit, but there's no port. You can buy kits to do the mod (they are solderless and look easy to install), and then when you perform the procedure to send patches to another unit over the sync cable, the added midi port sends out the raw sysex data as well. I'm going to buy one and install it very soon because I want to share some of my patches on the channel - I'll do a review when I have done it. Also, there are other ways to approach the problem that I'm looking into and working on in the background... But more on that as I get further along in my research ;)

+Paulo Duelli sadly not. It wasn't there on the DX7 so I guess that Korg made the decision not to include it. It would have been pretty great in the context of using it as a groove box though. You can get it close manually though, and then make sure the LFO key sync is turned on, that way it'll be nearly in time, most of the time!
