HiRes is an upgrade for the ModyPoly which adds high pitch resolution, microtuning and portamento. It works for Polysix and Mono/Poly (and is somewhat usable on the Poly-61).

Portamento

Portamento works in all play modes (unison, poly, chord,..). You can adjust the portamento time via the portamento knob, midi or the ModyPoly config menu.
Using the MODE switch on the Polysix you can select between:
– UP: auto portamento (will glide when playing legato)
– DOWN: Portamento is turned on
– UP/DOWN: Portamento is OFF.
Setting the portamento time to 0 is identical to turning it off.

You would probably only use this on the Polysix (Mono/Poly already has portamento). But of course it also works on the Mono/Poly and gives you midi control over portamento time. Portamento has linear constant time behaviour meaning it takes the same time to glide one semitone or one octave

Microtuning

The HiRes upgrade features full microtonal support for Polysix and Mono/Poly. HiRes uses a high quality 16 bit DAC which results in a effective resolution of 0.2 cent. Up to 4 tunings can be saved in the ModyPoly and recalled using the config menu. Real time sysex tuning messages are also supported and allow instant retuning of any note.

Voice spread

Voice spread detunes the individual voices in a controlled manner and allows a wide variety of effects. Slightly out of tune sound, or morphing between chords is possible. It is very similar to the ‘detuning amount’ parameter of the Polysex mod.
