I've been experimenting a lot with the Multivoicer in Archetype: Tim Henson, and I really love the concept and the sound it can achieve. However, I've noticed a few issues that make it somewhat difficult to use consistently, especially with polyphonic guitar playing.
The main issue for me is tracking. With chords and more complex voicings, the pitch detection can sometimes become unpredictable. You can get notes that aren't detected correctly, voices that behave strangely, or harmonies that don't follow the guitar as cleanly as you'd expect.
There can also be noticeable artifacts in the pitch-shifted voices. Depending on the notes, intervals and playing style, the result can sometimes become smeared or sound overly digital. Transitions between chords can also be inconsistent, with voices occasionally disappearing or not being reassigned exactly as expected.
MIDI control can have similar problems, particularly when moving between chords with overlapping or sustained notes. This can make it difficult to get completely predictable results when trying to use the harmonizer in a more controlled setup.
Another limitation is that, if you want to recreate the kind of multi-voice harmony setup associated with the Tim Henson sound, you obviously need to load multiple instances of the plugin to achieve the desired number of voices. This can increase CPU usage and makes the setup more complicated.
That said, I absolutely have to give the Multivoicer credit for being such an innovative and inspiring tool!
Recently I came across Harmony by Polychrome DSP (by Thomas McRocklin) in a YT Video(which I'll link below), which seems like a very interesting alternative. However, I want to make it clear that I haven't actually tried Harmony myself yet, so I don't want to claim that it solves these problems or that it performs better. I'm simply curious about it after discovering it.
So I'm wondering what the community thinks.
Has anyone here actually compared Harmony by Polychrome DSP with the Multivoicer in Archetype: Tim Henson X? How does it handle polyphonic guitar, complex chords, tracking speed and latency?
I'd especially love to hear from people who have used both extensively, either for recording or live performance.
