Hi Khew,
I've got 2 Poly6's, one with a CHD retrofit, and the other with a P6M kit from johannes, a member of this group.
Plusses and minuses are:
CHD kit
+ Easy DIY install, takes 15 minutes
+ Works reliably
+ Arp clock syncs to midi
+ Midi channel selectable, but set by default at factory
+ Cheap
- Midi in only
- Very basic
P6M kit
+ Full midi control of every parameter in realtime through midi (awesome)
+ Sysex patch dumps
+ Patch select through midi
+ Other functionality, like more patch storage and unison voice select (i.e. you can use it as a monosynth in unison mode)
+ I'm pretty sure arpeggio notes are sent over midi too
- It's an advanced install. The kit needs to be built by someone off a blank pcb (I got andrew jury from this group to do this). It's probably worth sending your keyboard to him to do the lot. This took quite a while.
- It's a fair bit more expensive
While I haven't had my P6M operational for long, it's a far superior kit IMO. I can tweak anything in realtime recorded to midi along with a patch dump, so It's almost like having softsynth (if you like that sort of thing) type automation and recall, but with that amazing polysix sound. The CHD kit is pretty basic, better than nothing though.
Hope this helps
Pete
