You can perfectly use a phone charger.
I also use a little external battery, these are pretty cheap.
I recently got such crackling sound with my JX-03, just lowering the main volume was sufficient to get rid of it. Haven’t had it in SH-01a and hope I won’t.
Just stumbled on this the other day and it’s great. The Roland manual is a joke. In true Roland form, they should have put some tylenol in the box for the migraine you’ll get trying to read it.
I’m enjoying this little guy though. Solid enough build, surprised by the heft of it. The smaller faders actually work really well for the size vs. pots. Sounds close enough and goes beyond what you can do on the original with faster LFO and poly.
Really nice sound there. I’m also fond of its sound and currently waiting for the keyboard attachment to appear in stock.
Only thing missing for me is HPF which would make pads sit a bit better in a mix but it also wasn’t in the original unit.
when i had my roland d-05 boutique module plugged into overhub i would get quite a bit of noise but when plugged directly into the wall using one of those apple usb power cubes it disappeared completely even at high volume
rytm , analog4 , octatrack , sh01a , 0 coast, moog mother , lots and lots of other gear barely used.
my digitakt does have some nice 101 samples dumped onto it.
i need to make significant use of the for sale thread , atmegatron , therapsid , acid 8 , patch blocks , se50,nord micro modular , kastle , meeblip anode and more.
