Took only 6 hours from drawing to ready PCB’s
Try that from China 🙂
The dsp-Gplug MK-II will run on the SSOP-16 chip.
Measuring 5mm x 6mm, this chip is even smaller than the dsp-G1 8-pin DIP chip.
The chip makes it the smallest stereo VA-synth in the world for sure!
The MK-II will also be available as a standalone SOIC-20 chip for those you that feel comfortable soldering SMT.
If you want to know how the dsp-Gplug is made, the documentation and source code is now available here:
The dsp-Gplug VA-synth inside a DIN-plug can now again be ordered prebuilt on the website http://www.dspsynth.eu
It is professionally built and delivered international for just $80.
For sure the smallest VA MIDI Synth in the world.
Here is the manual for the dsp-G1 synth chip.
It shows how easy it is to implement and use the chip.
Download here: dsp-G1 manual v1.0
I would say it’s definitely the smallest analog modeling MIDI synthesizer in the world.
A full VA-Synth in an 8-pin DIP chip.
I’ve sold 55 of them so it must be a hit? 🙂
All of the time I was thinking that people wanted a prebuilt DSP synth.
For the DIYers it is of course better to split the modules and let you build it yourself.
Here is the PCB for the 4 part multitimbral version of the dsp-G1 synth.
Yes, it’s 4 x dsp-G1 with supporting Components on a single board.
It has 4 synths recieving on MIDI channels 1 – 4.
If there is any interest in this I’ll order PCB’s for it and sell the kit at http://www.dspsynth.eu
The Alesis Q25 Microcontroller is a STM32F103C6 used for the keyscanning.
It’s an ARM Cortex-M3 @72MHz with 32Kb flash and 10Kb SRAM.
One could probably reflash it and run a VA synth straight on the chip but it would require to reverse engineer the MCU board to know what GPIO’s are used for the keyscanner.
