That was actually a reason why I haven’t used it for several months, yeah. I have started using it again now as part of a larger hardware setup with lots of battery powered things, using the Oplab of course. Pocket Operators are part of that, but also a Bastl Kastle, a Bastl Kastle Drum, one (soon two) Volca Modular, and a Korg Monotron and NTS-1 for fx and squelches.
The OP-Z on its own does sound somewhat sterile, there’s barely any dirt in there. The rest of that setup provides ample of that, so they complement each other really well IMHO.
The OP-Z in this context provides the master clock and stuff like pads or longer chord progression type things that the POs aren’t as good at, and it can also send CV to the Bastls and Volcas.
I’m still learning all the components and their interactions, but it’s a great little setup, and it’s all battery powered.
The OP-Z perfectly fits in there because of its strong sequencing capabilities and the CV. I’ll watch your Raspberry experiments with great interest because I think such a little thing would nicely fit into that setup, too - maybe for more fx, or as another more drone oriented sound generator.
I agree about the organ. IMHO it works nicely for little accents here and there, and it gets more pressure when it’s used as a bass or when there’s a big reverb accentuating it, but it isn’t really a church filling instrument on its own in its current iteration. It is already possible to use the LFO or automation to change between organ types, so I’m sure that’d work on the OP-1 too.
