This is the third video about the Volca Modular and it's all about hooking the Volca to other gear especially the Kastle 1.5 digital synth from Bastl Instruments. I think it's a pretty amazing combination! For more info about the Volca Modular make sure to check out the first two videos: walkthrough(   • Volca Modular:  Walkthrough  ) and Patching/LFOs(   • Volca Modular: Patching and LFO's  ).

TIMELINE
00:00 Robot Fight!

00:30 Whoops! The Audio Frequency LFO on the VM can be pushed to higher frequencies.

04:40 Using the Arturia BeatStep with the VM

06:00 BeatStep as a way to get DAW MIDI into the VM

06:35 Using the Arturia KeyStep with the VM

07:45 Using the Korg SQ1 with the VM

08:30 Discussion of the CV "limitations" of the VM, as is.

09:45 Discussion of the Kastle 1.5.

10:50 The Kastle I/O port gives 2 new CV paths for either input or output (or both).

12:00 Kastle Volca things from here on out. The Bastl Dude mixer is quite helpful in all of this. You also might want a couple of Ycables (stereo 3.5mm to dual mono 3.5mm) and maybe an inline attenuator (3.5mm TRS male on each end, an inexpensive one for headphones seems to work fine).

12:40 Grounding. It's not hard in this case. ADDENDUM: It looks like audioonly grounding (via the Dude) is fouled up by using an inline volume control, at least for the ones I have. So [I/O] to CVin is good, or both main audios to the Dude with plain cables is also fine

14:00 Discussion and an instructive patch.

25:15 Outro

26:30 Ender Volca Modular running through the amazing Transmisser reverb from Earthquaker Devices. Changing sequences and tweaking envelopes in realtime. There is some crackle and pop from where I hotswitched a pin cable to move the sequence quickly to a higher pitch (i.e. I switched from source.out to source.mod with the ratio set at an interval above). I WISH I HAD THOUGHT, at the time, about just using the Dude to crossfade the two signals. I may try that for an Instagram clip.
