Such an amazing synth for the price.
Monophonic is an interesting way for them to describe this synth. While it IS monophonic VA synth, it really feels like much more.
I'm an avid VA collector/user (JP-8000, Alesis Ion, System-1, Sledge 2.0, & MS-2000BR) and this is a very unique VA. Not because of it's shape, size, or unique appearance. The sound can be as simple as a standard 2-osc synth, or it can go literally insane. Up to 4-Osc with unison, the effects are unique sounding to say the least. The delay is very digital sounding and the distortion is...well weird. You won't get that Boss DS-1 nice tonal distortion or the gritty ear-piercing Korg distortion. You'll get more of this weird, hybrid distortion that's quite unique. The keys can be set to scales for live performance (I hate having laptops or tablets or whatever on stage). You can make some amazing drones with it.
The software is a must as you can get really deep into it. The sound is amazing. Don't treat it as a VA, if you're to take my advice. Treat it as a digital subtractive synth. It won't sound analog, however it won't sound as cold as digitals that you're used to. It is a truly unique sounding synth.
Fun to build (takes less than 10 minutes, no really, it's more like 2 minutes)
Months of sound design
you CAN build sound without the software, and it's fun to do.
$ for a 8-voice Modal mono synth? OMFG!
MIDI? Requires a software sequencer, without it, it becomes a pad box.
While you can build sounds without the software, there are many hidden features in the software.
Can't tell where the knobs are pointing so it's mostly done by ear, which can get difficult on the more intricate twiddling.
Protip: order some 6mm knobs with tightening screws. The pegs on the Craftsynth will fit a 6mm knob, this will save you migraines AND you can usually get 10 for $1 if you know where to look.
You'd be a fool to pass this up. In 10 years these will be sought after like the TB-303 was in 1998.
