Getting Started with G.I.M.I.C †You can move around this Wiki from the menu on the left. Pages marked (jp) are currently only in Japanese. What can I do with G.I.M.I.C? Which parts do I need? --- Here we'll answer these basic questions. What is G.I.M.I.C? †The G.I.M.I.C is a modular chiptune sound generating system: It can be loaded with various modules with sound chips that were employed in home computers and arcade games through the 80s and 90s.*1 By exchanging modules, it can emulate a range of chiptune sound systems. Currently, OPN3-L, OPNA, OPM, and OPL3 are available as sound chip modules. The G.I.M.I.C sound modules come with their respective sound chips already mounted, so you don't have to look elsewhere (or "scavenge") for them! What is it good for? †G.I.M.I.C can be used either as a song file player, or as a hardware synthesizer.
G.I.M.I.C can playback song files in a microSD card inserted to its card slot. Below are the file formats that G.I.M.I.C can handle.
When connected to a PC through USB, G.I.M.I.C can be used as an external sound source by software emulators and song file players. This enables G.I.M.I.C to play songs in formats that it can't process on its own. Where can I get it? †Currently there are two online retailers that sell our products, but we're afraid neither has got an English UI. They seem to ship overseas too, but we suggest you ask them beforehand to make sure. BEEP: Kyoritsu: Please try searching G.I.M.I.C to see if they are stocked and to check out the prices. Things to Prepare Before Acquiring Your G.I.M.I.C †USB Micro-B cable †To connect G.I.M.I.C to your PC. G.I.M.I.C also draws power from USB. For reference, below are the cables we employed during the development. Straight Right angled Note that some cables shipped with smartphones or tablets are "charge-only", i.e. unable to transfer data. A microSD card (if you use the "Standalone" G.I.M.I.C firmware) †From which G.I.M.I.C reads song files. We have confirmed that UHS-I cards can be used, but they will function in compatibility mode, since G.I.M.I.C doesn't support UHS-104. For reference, below are the cards we employed during the development. SanDisk MobileUltra microSDHC UHS-I 8GB : SDSDQY-008G-J35A An AC adaptor (for GMC-MB2PRO only; optional) †Drawing power from an external supply, you can avail yourself of G.I.M.I.C's full potential. Do not use an AC adaptor with an output valtage exceeding 5.2V, as it can cause permanent damage to G.I.M.I.C. For reference, below is the AC adaptor we employed during the development. AC adaptor for SONY PSP1000/2000/3000 series: PSP-100 G.I.M.I.C Modules: Primary †To play any sound with the G.I.M.I.C, you need a motherboard and at least one sound chip module (Lite motherboard can be used without any sound chip modules). Below are short descriptions of these primary modules. Click the names to see detailed descriptions. GMC-MB2: Motherboard †The heart and core of the G.I.M.I.C, the motherboard controls the sound chip modules with its 32-bit, 72 MHz ARM processor. It's also equipped with a microSD card slot to read data from, and a 3.5mm stereo jack for audio output. GMC-OPN3L: OPN3-L Module †OPN3-L (YMF288) is the sound chip employed in NEC PC-9821 in its later years. The chip is in some degree compatible with OPN (YM2203) and OPNA (YM2608), the sound chips of PC-6601SR, PC-8001mkIISR, PC-8801mkIISR (and the later models of the series), PC-9801 series, PC-9821 series, FUJITSU FM77AV series, SHARP MZ-2500 and so on. *2 GMC-OPNA: OPNA Module †A module mounted with an OPNA (YM2608) sound chip mentioned above. Just as SoundBoard II of PC-8801 series, this modules has a DRAM exclusively alloted for ADPCM synthesis, which makes possible an exact reproduction of PC-88 sounds. It also has a variable FM/SSG mix balance, which can be utilized to emulate sound systems of both PC-88 and PC-98 (86 SoundBoard). GMC-OPM: OPM Module †OPM (YM2151) is the FM sound chip of SHARP X1TurboZ and X68000, employed also in arcade game systems of 80s and 90s.*3 GMC-OPL3: OPL3 Module †A module mounted with an OPL3 (YMF262-M) sound chip, the FM LSI used by Adlib GOLD 1000, Creative Sound Blaster Pro 2.0, VIBRA 16 and Sound Blaster 16. This module can be used to reproduce the sounds of IBM PC compatibles in their MS-DOS era. Connect one of these sound chip modules to the motherboard, and your G.I.M.I.C is ready to play! G.I.M.I.C Modules: Secondary †Here is a list of optional modules to expand and enhance your G.I.M.I.C. GMC-OPT02: Digital Output Module for OPN3-L †This module enables direct digital output from OPN3-L. You can feed the signal into any external DAC of your choice and pursue the best end results. Ten-key †You can connect a ten-key to the USB Standard-A port of the motherboard and use it as an external controller to play/pause and choose tracks. We are not offering ten-keys themselves, so please acquire one (if necessary) through your preferred vendor. Future Projects †We at the G.I.M.I.C. Project are planning further development, both hardware and software-wise. Some of the projects are listed below. High-Spec Motherboard †A motherboad that can be loaded with multiple sound chip modules and control them simultaneously. The G.I.M.I.C with this motherboard will be able to handle up to 4 sound chips at the same time. Control with MIDI †Controllability from an external MIDI input, with which the G.I.M.I.C will be able to act as a hardware synthesizer. Inter-G.I.M.I.C Syncability †Ability for chain-connected G.I.M.I.Cs to be synced to each other to form an ensemble. Optimizations for Live DJ'ing †DJ-oriented features that will enhance live use, such as a CUE monitoring function. |
