Syntagm

This is a test of the June V2 chorus versus the Poly D chorus to ascertain whether they are similar or dissimilar.

Four chords are played:
1. Poly D chorus I
2. June V2 chorus I
3. Poly D chorus II
4. June V2 chorus II

The sound comes from the Poly D synthesizer (of course). There's some reverb, but that's the same for all sounds.

June V2 and Poly D chorus comparison

In this comparison, I now use a MonoPoly as a source, through the June V2 and the Poly D chorus (via the Poly D external input).

Four chords are played:
1. Poly D chorus I
2. June V2 chorus I
3. Poly D chorus II
4. June V2 chorus II
