The 3rd edition of Snyderphonics Mantas are scheduled to be released in mid-January 2016. Pre-order now for $50 off the price of $775.
The MantaMate (a Eurorack module that allows direct communication between a Manta and a modular synthesizer without the need for a computer) is in the testing phase, and is expected to be released in the first half of 2016.
The Snyderphonics JD-1 Custom Keyboard/Sequencer was shipped to the person who commissioned it. You can read the manual for the prototype model (with some features not yet implemented) here.
I am working hard on the MantaMate, a Eurorack module that will allow Manta users to perform without a computer, directly controlling analog synthesizers. It will also be able to act as a CV converter for USB-MIDI devices, and game controllers like joysticks. I don't have a set date for release right now, but stay tuned!
Spencer Russell wrote a fantastic open source library for the Manta. If you are a programmer and have an idea for some Manta software, this API will make it much simpler to talk to the Manta.
