I've been drooling over the Moog One, then started thinking about possibilities for next Sequential Analog Poly Flagship, as I'm a DSI/Seq superfan (PEK/P12/REV2 user). Here's my thoughts for some upgrades to the Rev architecture. Attached is a rough JPG mockup. High res link at bottom of post.
Start with the Rev2 as a basis... same chassis, keybed, and majority of osc/voice architecture and R&D work already done ~$2000 retail.
1. Upgrade the main screen to something significantly larger / higher resolution, like the Moog One screen. Adopt some interface design cues from Moog One... ie: the hardware button/pot layout around the screen is very logical and works well for quickly adjusting parameters. From a firmware standpoint, integrate preset catalog/categorization of presets, and have more visual feedback for all editing, sequencing and performance options. Basically, spend some time just working on firmware upgrades to the UI. Note: the screen does not need to be color if cost is significantly more... could just be backlit, single color. But higher res like Moog One, with similar control layout. +$400 retail?
2. For filter section, implement a Curtis Filter section, plus add a Moog Style Ladder Filter that can be routed in series or parallel (like in Moog One or Arturia MatrixBrute)... Having a Ladder Filter would fill some gaps and really round out the synth... for those Moog style bass and lead sounds. Dave Smith + Ladder Filter needs to happen!.. I think it will really bring in a new audience to DSI, who love Moog style bass/lead sounds.. the Ladder is really key. Possibly a State Variable Filter like the OB-6 for the #1 filter section instead of the current Rev2 Curtis. +$400
3. Expand the internal effects selection and routing/editing/mod destinations. It doesn't have to be Eventide quality, but I would love expanded control over effects and everything to be accessible from mod destinations. More reverb options, shimmer, more complex delay options, ring mod, choruses, phaser, flanger, rotary, bit crusher, more overdrive/saturation/feedback possibilities, and just generally more ability to modulate the deeper parameters of effects. +$200 retail?
4. Add some more controls for the Sequencer section (more like the Pro 2). +200 retail?
5. Add a ribbon for a little extra live performance control (like the P12). +$100 retail?
6. Add some more mod matrix slots... sixteen instead of eight. Also add an option for mod transforms like the Moog One.. seems like that is an awesome feature that is a fairly easy firmware task. +$200 retail?
Come in around $3500 for a new 16 Voice Analog Poly Flagship to compete with the Moog One, but at a much better price point. Maybe $2500 for 8-voice? I would buy this in a second, and probably a lot of others as well. The integration of dual filters in serial/parallel is really key to me, as I want to be able to capture a larger sonic palette in a single instrument. Also, a modern UI with easy drill down of advanced features is a must.
