Synthonia

The intent here was to release a preset board (with limited tweaking) that had the PC3 sound set in a lightweight low cost enclosure. This product was specifically requested by several of our distributors - no elves were involved in the decision making process, I promise.

We're hoping that the SP4-7's sounds will make it stand apart.

The SP4's architecture under the hood, while not accessible to users, allowed us to include programs that have a good deal more going on inside than what you'll find on some of the competitors' boards in this price range.

Many of the EPs and pianos use 10, 20 or even 32 layers (usually velocity switched, not simultaneously) which allowed us to imitate little details like release squeaks/thumps, extra harmonics, and all manner of acoustic and electromechanical goodness.

The effects, especially on the vintage stuff (EPs, clavs, B3's, CP80) are probably a bit better than what you'd find in this price range as well. And while I often take it for granted and forget to mention it, the reverbs are pretty stellar for any keyboard, especially a unit with a street price of around $1K.

Yes there had to be tradeoffs for the sake of cost and weight.
I much prefer an internal power supply, and I absolutely prefer the weighted TP40L. The good news is that this is not the only product we offer, nor is it the last thing we'll ever make. For those who want PC3 sounds but need more features or a different action, we now have a growing number of options, with the soon to be released PC3K, the PC3 and PC3LE series.

As far as I know, there are plans to release an SP4-8, with 88 weighted keys. I'll post again as soon as I have more specific info on this.
