"A high speed construction video of a MIDIbox SammichSID synthesizer.

From the MIDIbox website:
sammichSID was designed to be the “no excuses” MIDIbox SID synthesizer kit - i.e. for all those people who want a MIDIbox SID but consider building it with modules too time-consuming, too newbie-unfriendly and/or too hard to design and construct a control surface, and where MB-6582 is too expensive, too daunting and/or too hard to source all the parts.

sammichSID therefore has the following design constraints/features, which support each other:

* cheap
* small
* DIY newbie friendly
* minimal control surface
* single “walwart”/AC adapter supply, no C64 PSU brick!
* stereo SID, optimized for 8580/6582A, 6581 optionally supported
* “sandwich-style” stacked PCB design, no wires!
* laser-cut 3mm acrylic case by Ponoko, customization possible
* industry standard 2×20 character LCD with low-power LED backlight, customization possible
* common control surface parts used, customization possible

I forgot to add a music credit at the end of the video. The audio track is djynnx. You might know him from NOMMO OGO. If you don't, you probably should. His music is amazing.

"MIDIbox project in sammich format based around the venerable OPL3 chip, also known as the YMF 262, made famous by the Soundblaster audio cards of the early 90's."

Pictured is only one of four prototypes in the wild.

MIDIbox FM

"MIDIbox FM utilizies the Yamaha YMF262 sound chip (also known as OPL3) for generating the famous FM sounds known from Soundblaster (compatible) soundcards of the early 90s. In addition to the OPL3 specific features (6 four-operator voices, 5 percussion instruments) some software implemented modulation sources have been added to allow more expressive and very experimental sound creations."

Fmseq portable

YouTube via laboratoryf.

Details via this auction:

"The #fm_seq (portable edition) is a compact workstation that uses a special FM synthesis chip to produce tweakable sounds that can be sequenced with the included sequencer software. It uses genuine FM synthesis, not the sampled sounds you find with newer audio cards. It's 100% OPL3 compatible and is able to combine up to 36 operators so you can craft and tweak some extremely unique sounds.

Each channel features:

Main frequency (10 bits)Octave (3 bits)Note on/offSynthesis mode (FM or just additive)

Feedback (0-7, the modulator modulating itself)

For each one of the 4 oscillators: Frequency multiply (can be set to 1/2, 1 to 10, 12 or 15)Waveform (Sine, half-sine, absolute-sine, quarter-sine, alternating-sine, "camel"-sine, square and logarithmic saw)Volume (0-63, logarithmic)Attack, Decay, Sustain, Release (4 bits each, logarithmic)Tremolo (On or off)Vibrato (On or off)Sustain (On or off)Envelope scaling per key (On or off)Volume scaling per key (0-3) Vibrato depthTremolo depthPercussion mode (uses 3 channels to provide 5 percussion sounds)

You can easily maipulate the sounds in a live setting and the workstation itself is very portable. Another great thing about this workstation is that you can sit down and focus on programming your sound without the distraction of a million other programs in the background. This Item is completely unique, I built and modified both the hardware and software so this unit sounds really interesting... Watch the video if you want a good idea of what this workstation sounds like. It doesn't cover even a fraction of what this is capable of but it should give you an idea.
Everything comes setup and ready to go.

The software is incredibly easy to learn and understand....you should be able to start making music within an hour of turning the workstation on. UPDATE: A few people have asked if it is able to produce sounds similar to Commodore 64's chip music. The answer is YES....the sounds from this workstation are VERY comparable and in fact more capable since it uses 36 operators to create custom sounds. This new version is 100% compatible with all previous versions."
