One of the add-ons to the H5 board was the header for an internal MIDI board. The idea is to be able to plug in a MIDI board like the S2 / X2 DreamBlaster that automatically taps into the MIDI line and outputs the audio through the monitor audio line alongside the YM chip sound. In addition there is a header to tap off the L/R audio.

We would like to thank Serge from https://www.serdashop.com who provides S2 and X2 DreamBlaster boards for donating to @exxos and I some X2 boards to support the effort.

Below is info on each board and in situ:

S2 DreamBlaster is a Waveblaster compatible synth module based on the SAM2695 chip with combined wavetable and FM synth sound for a high end retro sound. 64-voice polyphony (without effects) 38-voice polyphony + effects High quality, compact size CleanWave soundset General MIDI compatible effects 4-band stereo equalizer Low power consumption, only 5V supply required (no +/- 12V) Low noise audio output Can be used on Waveblaster compatible soundcards Can be used for electronics projects, such as arduino, raspberry pi, midibox,... Very small size, ideal for building into projects : 24mm x 34mm SAM2695 MIDI specifications and chip datasheet : click here. Cheap but brilliant replacement for the more and more becoming less available GM-daughterboards like famous Roland SCB-7 or Yamaha DB50XG. https://www.serdashop.com/waveblaster

X2 snippet playing MIDI on H5

Just had an X2 and S2 delivered today as part of a black Friday bundle.

I've got the X2 installed on the H5 and consider me impressed so far.

I've just hot to find some decent midi files to give it a good trial.

Hi @Icky,

I'm curious about something: how did you install the Gotek on top of the X2? I just did a fit rehearsal in my case, and it does not seem to fit... the Dreamblaster board is too tall. Of course, I could put the Gotek higher, but then the FDD hole in the case is not aligned.

Thanks,

Andres.

@AndresPlazaR - I think there are a few case variations around the floppy.

The case I have requires the longer floppy mounting posts see example pic below. Could you share some pics in your build blog https://www.exxosforum.co.uk/forum/viewt ... 3&start=30 so we can see the difference.

First show the case floppy lugs on the right side of the case where the gotek rests on:


Second shows how tall the posts are for my case (18mm) and the gotek resting on the lugs on the right:


Third shows the case closed:

A few more demo midi songs.

tempted on this myself, any volume issues with an h5 ?

I believe so as they are the same pinout.
