Midibox MB6582 Maxed Out w/ Eight SID 8580's

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Midibox MB6582 Maxed Out eight SID 8580's C64 MIDI Synthesizer Rare!. Condition is Used.It's maxed out with eight 8580R5 SIDs. Beautiful blue panel from Julian (which has some scuffs) and white LED's though not too bright. A nice illuminated fan on the back with the "overdrive" pots. Loaded with latest firmware. Has the clear custom plexi window to protect the LCD display. Includes original C64 power supply. The encoders do tend to "bounce" but from my understanding it's normal, and totally manageable if you don't twist too quickly. Like I said, there are some blemishes, priced accordingly." $700 at the time of this post.

Hawkeye - Chiphead (Stereo SID Acid)

Published on Apr 13, 2019 Hawkeye

"It has been a while - we have moved and i had to do a quick new studio test - using some original MB6582 'acid' basslines created by TK./Thorsten Klose. Many, many thanks! :)

This was done in only about two hours and is not really a full track (thus the new midiphy SEQ v4+ was mostly unused). It is more of a SID stereo bassline audio demo, highly repetitive. I've also added both video takes, i am not sure which one is better or if both are bad, please tell me what you think :).

In this video, most sounds are created by DIY devices:
* MIDIbox MB6582 for a pair of 8580 SIDs in stereo bassline mode
* Mutable Instruments Anushri for the lead
* midiphy LoopA prototype for sequencing
* DIY polivoks stereo VCF to filter the drums

Recorded directly onto a Tascam audiograbber, no DAW was used, only slight audio compression added in post production.

Non-DIY equipment used:
* Vermona DRM 1 for drums
* MFB Dominion I as a secondary bassline synth

Many greets and thanks for listening and watching!

Introducing the MIDI to CV Converter (MBHP-CV) and a quick repair

Published on Jun 23, 2018 Sbranvlztronics

"The MIDIbox CV can convert MIDI messages to 8 CV and 8 Gate outputs. I added a monophonic analog synthesizer (VCO, VCF, VCA and VCADSR) to the MIDIbox so it can be used stand alone or controlling external analog modules.
I was having trouble with the menu navigation switches, so I replaced them and made this video showing the internals of the MBHP-CV.
A future video will show it at work.

Midibox Sequencer MBSEQ V4 Build for Modular on ECALPEMOS|NL


"I discovered the Midibox sequencer MBSEQ V4 via a forum post somewhere and was immediately interested. It’s a project of Thorsten Klose and lots of people have added code and hardware modules to it.
For more information check out the following websites.

The main thing that made we want to build this sequencer was the modular approach. You can build your own custom system and are not limited to a predefined configuration.
I wanted to be able to control MIDI equipment as well as modular synthesizers and this is pretty easy to do with the MBSEQ V4."

LoopA - DIY MIDI Looper Introduction (MIDIbox platform)

Published on May 7, 2018 Hawkeye

"After about three years in the pipeline, we are proud to announce the LoopA v2 [you can find a post from 2015 here]. Thanks to Andy, there are now PCBs - and we have also finished a DIY acrylic case. Public availability (PCB and essential kit for hard-to-get parts) is expected somewhen in June/July, also John from did show interest and wants to resell those boards for the U.S. based folks!

The LoopA will definitely not be a beginner DIY project, as some SMD soldering and somewhat precise board interconnection work is needed, but a BOM and a full documentation about the build process will be released, so it should be doable :-). On the plus side you will receive a very compact unit (only 38mm height packing three stacked PCBs), a lot of MIDI interface functionality and a very responsive system that is designed to be "easy to use" and inspirational. Like not starting up your DAW and updating drivers but just sitting at your favourite synth and hacking in some lines! :)

Here are the main features:

* six polynote tracks linked to individual MIDI configurations
* six scenes, allowing for a total of 36 in-memory MIDI clips
* graphical note display on an OLED, that shows clip notes and also edit changes like transposition in realtime
* four MIDI OUT ports, two MIDI IN ports, one OUT port is configured as an optional BLM expansion port (later)
* non-step sequenced recording, clips can be dynamically requantized during live sessions
* note-editor for fixing recording errors
* transposition, scrolling and time-scaling of clips
* disk operations (full recall), storage to SD card
* BPM setting and MIDI sync from "upchain" devices like a master MBSEQ

Upcoming DIY midiphy LoopA MIDI Sequencer - Hawkeye - Microwaved (Waldorf Microwave 1, SID 8580 and friends)

Published on Apr 28, 2018 Hawkeye

"Hi, it has been a while...

This song sat on the sequencer for far too long - there were too many different melody lines going on and it was really difficult to bring it together - while i am not 100% convinced, it is the best possible effort with the midi clips i came up with, i hope you still like it - it had to be finished at some point, otherwise it would have occupied the sequencer for another few months :)

It was live sequenced on the midiphy LoopA - this small 'inspirational MIDI sequencer' will be available as an affordable DIY kit soon.

Other hardware used:
Dreamy string: Waldorf Microwave 1
Simple Lead: SID 8580 in MBSID/MB6582 synthesizer
Arpeggiated synth: Alesis Andromeda
Bass: MFB Dominion I
Second Lead: Roland V-Synth
Drums: Elektron Machinedrum
Audiograbber: Tascam DR-100
FX: Strymon Timeline and BigSky

Recorded directly from the hardware, only audio-compressed in post-production, but no DAW was abused during recording :).

Many greets to all DIY folks out there, you know who you are, thanks for your support and time!

I might be uploading a few DIY videos (e.g. how to build the LoopA sequencer used in this song) in the next time, if you are here only for songs, please don't go away, there will be more, later on :).

Thanks for watching and listening,
Hawkeye / Maelstroem Records"

TR-9090 driven by Midibox drum sequncer

Published on Mar 27, 2018 wotatwaat

"TR-9090 driven by a Midibox drum Sequencer that Thorsten from Midibox kindly modified so the firmware supports individual accent for the voices. It is a fantastic sequencer. The Tr-9090 has a few mods, CV control for various parameters. Here the Beatstep is controlling the pitch of the bass drum and occasionally the hi hats. The hi hat eprom has been expanded so you can switch between standard 909, 808, or flanged hats. Noise frequency, Clap reverb amount, tune, filter. Rimshot tune and a few more."

Unique Lego Cased Midibox MB-6582 SID Synthesizer w/ R2-D2s

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"This is a rare chance to get a MB6582 SID chip Synthesizer.

The MB6582 is an extraordinary DIY synthesizer based on SID chips known from the famous C64. More infos here:

The synth was assembled by me, works perfectly and is in a very good condition! It is a very unique *Lego Edition* - only one of it's kind!

Case and potentiometer knobs are made of Lego (suitable for SIDchip sound)
The display is in 'rusty-orange' and matches the orange flat-top LEDs.
This MB6582 is also expanded with a custom active mixer circuit (+/-12V supply). It has a main L/R out, volume-pot for each engine and a Stereo/Mono switch for each engine.
Single outputs are switched, i. e. if a single output is connected to a jack, the signal is not routed to the mixer (can be changed internally)
Following chips are built in at the moment:

4 SID 6582 (1x stereo engine and 2x mono engine at the moment)
3 cores (4th core included)
The MB6582 can be expanded to 4 stereo engines by adding another 4 SID chips (SID 6581 / 6582 / 8580 - beware 6581 needs different voltage set by jumpers internally). In stereo mode 2 SID chips are used for L/R channels seperately to generate more space! i.e. by controlling filter cutoff seperately for L/R channels.
This MB6582 requires a power supply which supplies +12v/+5V/-12V/GND. I built my own specific power supply around a MeanWell RPT-60/100kHz, it can operate from 90-264VAC.

Since I am not an electrician I have to ship my power supply dissassembled and buyer must reassemble it at his own risk! (it's a very easy process!)"

Spectral Arpeggiator: PC - MidiBox CV - Matrix Analog Synth

Published on Nov 22, 2017 Sbranvlztronics

"Simple patch presenting a 'Spectral Arpeggiator'.

In this video a PC running a MIDI sequencer sends data to a MidiBox CV converter, which then controls the Matrix synthesizer patch.

The master Voltage Controlled Oscillator (VCO) determines the fundamental frequency, and the synced slave VCO is sweept for harmonics using very short notes. The slave VCO triangle output is sent to the Voltage Controlled Phaser, VCA and finnaly to the Voltage Controlled Delay. The wet/dry mix of the CV Delay is controled by midi velocity, CV Phaser cutoff freq. by a local LFO. Tweaking the ADSR potentiometers create some nice variation in the textures.

Hope you enjoy, thanks for watching.

B.H.Z. Quad Sid

This was one spotted on, by swissdoc. According to the listing it's a:

"C64 SID Synthesizer 4x SID Chip

1x Midi In
1x Midi Out
4x Audio Out Mono je SID Chip 1 Audio Out"

If anyone knows more about this one or B.H.Z let us know! This is the first B.H.Z. post on the site.

Curious if this is a one off Midibox based SID.

Update: confirmed this is Midibox based. Now checking on what the B.H.Z. stands for. Maybe the initials of the maker.

Giana 64: Commodore 64 Keytar Published on Feb 25, 2010

"A quick demo of a keytar I built out of a Commodore 64. It uses two SID 6581 chips and was made using the Midibox Sid platform from Better video to follow later." See here.

via this auction

"Up for auction is a unique electronic musical instrument, The Giana 64. Giana is a custom MidiBox SID v2 built into a keytar form-factor using an original Commodore 64 case for the body. The build includes several unique additions to the standard Midibox SID, including an assignable ribbon controller, expression pedal input, CV inputs, and of course the integrated keybed. A full MidiBox SID control surface is integrated into the neck.

I built Giana in the winter of 2010. It was a true labor of love, being one of the first large-scale electronics projects I ever worked on. The first video I posted of Giana went quasi-viral (by 2010 standards) and was covered by numerous synth blogs including Synthtopia; as far as I know it remains the only MIDIbox SID ever built into a keytar form-factor.

I tried to design it to look a little like a ghostbusters proton pack—some of the “retrofited” elements, like the rainbow ribbon cable running across the exterior, are not actually functional, but were fit for a hax00ry, cyberpunk vibe.

The instrument can be used flat on a table, or worn upright using the built-in strap buttons. The entire system is mounted onto a single piece of solid wood, and the plastic components are attatched with metal hardware, making it quite sturdy / gig-able.

Please note that for aesthetic purposes, the majority of the controls have been left unlabeled. The neck layouts are uniquely spaced, so that with a little practice all the major functions can be easily memorized. A PDF will also be provided labeling each function, to be used in combination with the official Midibox SID user manual.

MIDI Box SID V2 including standard MIDI I/O
Full control surface including mod matrix
Dual 6581 SIDs in stereo configuration, hand matched for similar filter characteristics
Integrated keyboard
Assignable ribbon controller (range-centered for use with pitch bend)
3 assignable CV inputs, 0-5V range, diode protected (plug and play with Euro modular)
Assignable expression pedal input
Custom power supply (not a recycled c64 PSU) provides robust power
Ships in custom case with custom foam inserts (see pictures—adapted from a rifle case)

Included Items:
Giana 64 Keytar
Custom PSU
Custom Carrying case
Moog EP-2 expression pedal
Rainbow guitar strap
Interface guide PDF

The instrument is in excellent condition, having been privately owned for 7 years, with about 3 of those years spent in storage. In preparation for the auction I tested every function and all systems are nominal. Since this is a DIY project however, the instrument is being sold as-is. Potential buyers should understand the responsibility that comes with owning a DIY instrument.

The pictures were taken a few days ago and reflect the present condition of the instrument. The linked youtube videos were recorded back when the instrument was first built. Not much has changed since then except for a few minor chips in the paint."

Hawkeye - Neutron Blender (MFB Dominion I and friends - live)

Published on Jan 27, 2017 Maelstroem3

"Test-driving the MFB Dominion I and some friends, live-sequenced on the MIDIbox sequencer V4! :-)

I recently removed my computer/DAW from the synth setup, as I don't use it any longer (indeed i never used it, since the MBSEQ was finished many years ago :-)). The space that was occupied by the display was now available for another synth. After some long research and considerations, i chose the MFB Dominion, as I think it offers something new for me. In short words: it is fantastic! I still have to explore it more in-depth, as has a really powerful synthesis/modulation engine, but the first weeks with it were awesome! Thanks, MFB! :-)

Gear used:
Mono analog lead #1: Dominion I
Mono analog lead #2: Alesis Andromeda
Mono analog wall of noise: Moog Little Phatty, live controlled by the MBProgramma Patch Editor
Dry FM bassline: Yamaha FS1R, live modulated with the onboard encoders
Warm analog-ish (but fully digital) portamento pad: JD-990 through Polivoks DIY VCF (the left filter knob in the video... Thanks, J! What a deal, both of these are truly awesome!)
Drums: Elektron Machinedrum UW
FX: Strymon Timeline and Bigsky
Mixed through a Mackie 1604, directly recorded on a tascam .wav-recorder.

Thanks for watching and listening!
