Tag: midi

Recreates an Atari 8-bit computer for an Atari 1050 case with integrated IDE storage, expanded memory, PS/2 input, video, stereo audio, MIDI, and expansion.

The maker publishes schematics, a BOM, firmware, panel files, and production Gerbers. The project page links to The Brewing Academy for boards and assembled systems; verify current stock on the seller page.

Recreates a Passport-compatible MIDI interface for music software on Apple II computers.

The store showed one card in stock on 2026-07-24. A complete setup requires a 48K or larger supported computer, display, floppy drive and controller, compatible MIDI software, a MIDI instrument, and two 5-pin DIN cables.

Connects an Apple IIgs serial port to MIDI instruments using Apple A9M0103-compatible software.

The interface was out of stock on 2026-07-24. It requires compatible MIDI software, a MIDI-equipped instrument, and two 5-pin DIN MIDI cables.

Turns a C64 or C128 into a stand-alone SID synthesizer with keyboard performance, real-time controls, MIDI support, and optional six-voice stereo.

Protovision showed 12 orange Cynthcart 2.0.1 cartridges in stock at EUR 38 with a one- to two-week shipping estimate on 2026-07-28. The maker also publishes ROMs and source for personal use, but does not permit third-party cartridge sales. The project page labels 2.01 current while also listing a 2.0.2 source reorganization, so check the included ROM revision if that distinction matters.

Connects a Commodore expansion port to external MIDI equipment through MIDI In, Out, and Thru sockets.

Human review confirmed on 2026-07-28 that the linked seller item is currently orderable. The seller says the cartridge includes instructions; Cynthcart, an expander, software, and MIDI cables are separate.

Adds a Dream-based hardware wavetable synthesizer with licensed Roland GS samples to an ITX-Llama.

The RetroDreams page reported Sold out on 2026-07-27. It describes this Special Edition as a limited-time ITX-Llama exclusive and retains old copy saying that the batch would ship in February 2025.

Adds a self-contained SAM2695 General MIDI sound module to an Atari ST-family computer's MIDI output.

The product page exposed a login-or-register-to-buy path on 2026-07-27. The box contains the cased module with an attached short MIDI cable, but the 5 V Micro-USB supply and speakers or headphones are separate. The seller identifies Atari ST use but does not prescribe player software; choose an Atari application that sends compatible MIDI data through MIDI OUT.

Adds an SIO-connected General MIDI file synthesizer with external stereo output and Atari audio mixing.

The product exposed a login-or-register-to-buy path on 2026-07-27. It is a MIDI-file synthesizer, not the MyTek MIDI input/output interface already in the catalog. The public page and human review provide no written player-software, file-workflow, or model-specific SIO-audio instructions. Treat the external stereo output as the documented playback path and confirm software availability before purchase.

Multifunction 50-pin SCSI-2 device that emulates hard disks and CD-ROM drives from SD or MMC media.

The Tindie page exposed quantity and CD-audio-jack selectors with a current View Options and Buy path on 2026-07-24. Its destination-dependent shipping messages were inconsistent, so buyers should confirm shipping for their country.

Combines an integrated MIDI interface with five cartridge-resident SID music applications for sequencing, synthesis, drums, and low-fidelity sample playback.

The official contact page reported MSSIAH in stock on 2026-07-28, and its online order workflow was live. The cartridge and software are one integrated product: its MIDI hardware cannot be used by other applications, no MIDI OUT is provided, and the ROMs are not sold separately. A monitor is effectively required, and saving needs a compatible drive or separate Savyour.

Adds low-latency Roland MT-32 emulation and SoundFont synthesis to an ITX-Llama or MIDI-equipped vintage PC.

The preconfigured RetroDreams package reported Sold out on 2026-07-27. The GPL-3.0 upstream project still provides source, releases, and setup documentation, although its maintainer says further releases are unlikely. Users must supply legally obtained MT-32 or CM-32L ROM images; they are not included in the retail package or upstream download.

Connects MIDI instruments or an optional DreamBlaster wavetable module to an Atari 8-bit computer through SIO.

The storefront family was sold out on 2026-07-24, but MyTek publishes schematics, Gerbers, firmware, and bare-PCB order links for SIO2MIDI and SIO2MIDI-S2. SIO2MIDI-S2 does not route its synthesized sound through the Atari; use its headphone or speaker jack. The maker page also includes 1088XEL-only MIDI-XEL variants, which are not attached to factory-computer entries.

Expands a 576NUC+ to 1088 KB and adds a real-time clock, A8PicoCart, SDrive-ng, and optional FujiNet networking and MIDI synthesis.

Revised Gerbers, schematics, BOM, datasheet, firmware, and case files were published in March and April 2025. The maker says The Brewing Academy will offer assembled and DIY parts, but current seller stock was not verified in this pass.

Breaks out a vintage PC gameport for two joysticks plus simultaneous MIDI input and output.

The JCM page showed six units in stock on 2026-07-24. MIDI requires an MPU-401-compatible gameport, such as one on an appropriate Sound Blaster 16-era card or clone. The required male-to-female DB-15 cable is not included; a bottom insulating plate is included.

An 8-bit ISA card with switchable classic sound-card modes plus MIDI, USB game-controller, and CD-ROM emulation.

Joe's Computer Museum showed the assembled PicoGUS 2.0 in stock on 2026-07-24. The official site also listed stocked UK and EU sellers. Open design files and build guidance remain available for people who want a DIY board.

Adds SAM2695 General MIDI synthesis to a sound card with a compatible Wave Blaster header.

The Lotharek page exposed a login-or-register-to-buy path on 2026-07-27. It identifies the sound-card wavetable header but does not publish a tested-card list, connector-orientation diagram, clearance envelope, or host mixer and software setup. Confirm that the sound card has a correctly keyed or clearly marked Wave Blaster-compatible 26-pin header, identify pin 1, check daughterboard clearance, and power off before installation. Do not assume an arbitrary 26-pin connector is compatible.

Uses a Raspberry Pi cartridge to emulate memory, sound, cartridges, ROMs, and file-loading functions across several Commodore 8-bit systems.

The open project publishes Gerbers, BOMs, software, and case files for full-size and Zero boards. Retro-Updates' assembled Sidekick64 Zero was out of stock on 2026-07-27 and excludes the Raspberry Pi Zero 2. The maker calls the project a personal playground and warns that unsupported images, timing glitches, and unsafe cartridge combinations remain possible.

Recreates the 1989 Sound Blaster 1.0 with digital playback and recording, AdLib-compatible synthesis, CMS audio, and a joystick/MIDI port.

This is a self-assembly project. Follow the documented bodge resistor, MIDI jumper-wire, firmware, DMA, IRQ, joystick, and I/O-address instructions before use.

Combines ROM and program loading, MIDI, Ethernet, NFC launching, remote control, a real-time clock, and REU functions in a Teensy 4.1 cartridge.

The maker's Lectronz store showed six fully assembled revision 0.4 units at USD 64.00 on 2026-07-27. The programmed Teensy 4.1 and case are included. A CR1225 battery is included only with United States shipments, and an SD card or USB drive is needed for content beyond the built-in files.

Adds MIDI In, Out, and Thru, RS-232 communications, programmable flash, and UltiMem-compatible RAM expansion to a VIC-20.

The RETRO Innovations store exposed an Add to Cart path at USD 65 on 2026-07-28, although its current-stock field was blank. No enclosure is included. Supply a 5-pin DIN MIDI cable and use the downloadable VIC-MIDI software; the project page also publishes EAGLE 6 design files and a bill of materials.
