I'm not entirely sure here but I assume part of it has to do with converting the samples and treating them like an oscillator signal to send through the analog filters/components. That's my guess anyhow.
I suspect there will be some more in-depth news coming soon.
Pretty sure folks will like the Sample Oscillators.
I’ve got 4 @ 96k on my Solaris.
I might use 2 at most but usually 1 Sample, 1 Waldorf Oscillator, and either Prophet VS or multi wave CEMs.
For 4K you should get a 4 Oscillator synth.
But DSI Gear usually gets big and snappy with a pair.
I’m just use to so many EGs (6) LFOs (4) and Oscillators (4).
I’d grow weary of 2 win 8 voices.
A Prophet XPander would be fierce though.
