What I would enjoy:
A sampler with instant or peri-instant control of
- sample start
- sample end. Can be as short as a wave cycle.
- loop on/off. Repeat #
- Reverse. Perhaps applicable to selected portions
- Ability to quickly append a few samples into a composite "wave". With flexible selection of component wave sections. (Attack of one, sustain of other). With cross-fade controls. (Maybe 16-32 total "slots".)
I.e., an instrument dedicated to sampling. Via analog filters. Terrific knob-button laden UI.
With characteristically thoughtful DSI-style programming features. Like found on Rev2 or P12.
- parameter sequencer
- performance sequencer
- Delay play
- And LFO's
Always fun!

RAM vs flash rom workflow/costs. Enough (but not too much) of both. This is one of the tough spots about this endeavor. Memory size & kind is a fundamental cost question. What are sweet spots for RAM (for editing) and Flash Rom for quick-access playback. This is the topic that will garner such complaints from the clueless- making useless comparisons to computer based systems. I admire makers who have the stomach for that vitriol.

The other tough thing:
-- DSP/coding that's responsive for that level of complexity
-- screen. Which way is enough for flow, and not too much. I would think a simple LCD/OLED style screen will suffice. It can't have it all and match price point, development, and workflow needs for a wide enough market.
It's so much easier to write a forum post. My hats off to successful designers who succeed off their designs!!!
