Roland SH-101 VS My 101-VCF Noise Floor (and What to Do About It)

Today a quick noise floor comparison of the Roland SH-101 versus my 101-VCF under no-input conditions. I've boosted the no-input signal condition by +6dB to emphasize what is happening. And what you can do silence the noise when you don't want it there. I'm hoping that in making this video that it will help discern what is normal behavior to be expected for the modules, and what is not.

Kawai K1m Retro Digital Synth Euphoria Desktop Module

Today I'm auditioning my original patches made for the Kawai K1m. A very limited digital synth from the 90s. And yet after digging into the architecture was able to harness some very powerful and unique features that are really, I mean, REALLY surprising. You'll hear some cheesy things, some pads, basses. And then there's fat poly action, swirling digital synth soundscapes. And alive motion things that are frankly astounding for such an unassuming little black box. Try to keep in mind when you hear the Mesmerized patch - the K1m has no sequencer nor arpeggiator. No freely assignable LFOs, just a fixed vibrato and that's it. And NO filter ha! Be sure to watch the whole video, lots of my favorites are on the 2nd half starting @3:19. My favorites are Head East, LA Sunset, Liquide and Mesmerized...which ones did you like?

Introducing my Spring Tank Reverb Driver version 2. Same great sound and features as before. But now in 4HP with added Feedback knob. The Drive setting is now a trimmer on the PCB Set-and-forget. In today's video I will be auditioning the module with a few different spring tanks and various patch scenarios. Like pairing the reverb with Synthrotek DLY.
