Hello all, I have an issue with my new sh-4d that I’m curious whether it’s an unique issue to my particular device or is common to others…
If I power my device to a powered USB computer hub or direct to the computer in any combination I can hear a grounding hum – the only option I’ve found that I can get the hum to disappear is to power the sh-4d with batteries or a USB power bank… which is fine, but when I’m working with the sh-4d in the studio, it would be better to power it with a constant electrical source which I have not figured out how to do without the hum which shows up…Read More4 Comments-

Yes it’s a common problem when powering synths from the PC USB port. I have experienced it with my Roland SH-4d and T-8, and the Uno Synth Pro. As @kpatzsc said, it’s best to power separately if you can. I’ve also seen people recommend using a USB isolator so maybe worth having a look at something like this… https://hifimediy.com/product/usb-isolator/

Polyend have released the Tracker Mini. Looks cute. No pads or jog wheel, but has more sample RAM and bigger CPU, and can handle stereo samples. I’m interested but it’s $700 (same price as the desktop version) which honestly seems a bit pricey to me.

I have the regular Tracker, which is great, although I don’t use it much. I’d consider the handheld version but the button layout looks awkward. I think I’ll wait and see some user feedback. I agree it’s also rather expensive for what it is.

Shame they couldn’t have included some of the pads for note input

He didn’t actually seem to be all that impressed with the Tracker Mini, but nice to have some more demos finally. Seems like it’s been a long wait on this one. I do agree with what he says about the filter. I don’t know what it is about the Tracker but I never think it sounds that good when used with my other gear.

This is a common issue on many of Roland’s USB powered synths. AFAIK, you could try a USB isolator cable, or use a separate USB power supply like a phone charger to power the SH-4d, and use DIN MIDI instead of USB.
