Aaron Andrew Hunt from H-Pi Instruments in Germany), Tim Alex Jacobs (mitxela · UK) and Jordan Dimitrov Petkov (Largonet Ltd., MIDI Boutique · Bulgaria have teamed up to create the world's smallest polyphonic MIDI instrument. It's really incredibly powerful.
FLASH draws its power straight from the MIDI socket! All MIDI OUT ports which are made to the specification of the MIDI Manufacturer's Association (MMA) will work. MIDI OUT ports not made to the MMA spec will not work!by H-Pi Instruments
FLASH features unlimited dynamic General MIDI microtuning for ease-of-use with 16-channel polyphonic tuned output from TBX2, TBX1, and Tonal Plexus TPX keyboards, and also features a mini UART-programmer which allows you to assign unique microtonal tuning tables to each of 16 MIDI input channels for full microtonal output compatibility with literally thousands of standard MIDI controllers as well as multichannel controllers like MIDI guitars and MIDI organs without a tuning device, not to mention advanced 2048 unique-pitch-output for the Tonal Plexus and other microtonal controllers like the Microzone, Axis 64, and Terpstra keyboards. Of course you can also use it as a normal synth with normal tuning ... if you're into that sort of thing.
The FLASH UART-programmer interfaces via USB with Universal Tuning Editor (UTE) cross-platform software (free license included), so you can edit tunings and upload them to the synth. Firmware is also user-upgradable via the programmer, so features can be improved or added at any time.by H-Pi Instruments
In fact the Flash comes with the UART-programmer, USB cable, and a UTE software license.
