I mean, I’m sure it gets used that way. But you can see the benefits of having a number system that counts in cycles of 16 when primarily making 4/4 music in bars of 16 steps, right?
That’s kind of the LSDJ/M8 story in a nutshell, actually. None of the UI was “engineered”, as you say. The entire experience was a hack constructed under the immense physical and visual constraints of a Game Boy as a way to use it as a music production system which, honestly, would be an absurd thing to try to engineer in the first place.
But weirdly, something about it really worked. Like, even after all the constrains were lifted, people still liked the feel of making music that way. True, it was more discovered than engineered. But what was discovered was no less true than if a committee of civil engineers has spent a bunch of time methodically iterating towards it. It’s just, because we stumbled upon it, we don’t have the paper trail of years of specs to explain exactly why it’s nice. Nor do we have the proper batch of affordances to on-board people seeing it for the first time.
It’s like the web. Berners-Lee made the web browser under the intense networking, compute, and UI constraints of NeXTSTEP. It succeeded beyond anyone’s wildest dreams, but wasn’t engineered to. It was discovered. It took a decade for Fielding to come along and dissect what accidental things done by Burners-Lee actually made it successful (in the form of REST).
I suppose LLDJ/M8/etc. are waiting for their Fielding to break down what about the design is really a necessary component for mobile music creation and which parts are just old constraints and/or gatekeeping.
I’d really love to discuss this more on the M8 thread, actually.
But, to keep the OP from getting grumpy:
I can’t think of anything that does virtual analog, FM, macro, and samples like the M8.
If you drop the FM and redefine “sampler” to be “ROMpler + small space for user samples and loops”, the Roland MC-101 checks most of the boxes. Small. Can run on (disposable) batteries. Has pads, pots, and faders. Contains quite a nice step sequencer with clip-based arrangement. The pads are reasonably playable but have arp/chord/scale modes, too. Motion recording without trackery spreadsheets.
I wouldn’t say the process of sound design is nice or comfortable. I think the average person would find it much more a nightmare than coming cold to the M8. But it’s possible. And sticking to presets, everything else about the box is very enjoyable.
Or what about the Circuit Tracks? My experience here is limited to the original, but the Nova synth engine is a lot of fun. And there’s lots of room for one-shot samples. Sequencer is super solid, and you certainly can’t complain about a lack of pads or knobs. Maybe not exactly portable… but it has a rechargeable battery. So feels portable in spirit, at least.
