The trouble with this method is illustrated by the drums heard in the opening music to Leisure Suit Larry 3 when playing this game on an IMFC using the IMFC.DRV. But it could not use this command in its FB-01 driver, it had to use the earlier method. As Sierra used the Parameter List Transfer command for its IBMFC driver, all MIDI channels are assigned the proper number of notes. The IMFC can use this method, but it can also use a System Exclusive command called "Parameter List Transfer" to set all the Instrument and Note assignments for all sixteen MIDI Channels at once. Then it used a System Exclusive command called "Event List: Parameter Change" to set the number of notes assigned to each MIDI Channel. In order to have total control over Instrument assignment to MIDI Channels, Sierra used a System Exclusive command called "Parameter Change by System Channel + Instrument Number".

You can use a Program Change command to change the Instrument on a MIDI channel, but it can only select from the 48 instruments in the voice bank to which the instrument belongs. The FB-01 really has rather rudimentary support for MIDI commands. Multiple oscillators can be used at the same time for more complex sounds. This limitation exists because the YM2164 has eight 4-operator FM synthesis oscillators. Only up to eight notes can be played back by these devices at a time, so the note pool can easily run out if multi-note instruments are being used. However, in order to hear an instrument, the FB-01 must assign one or more notes from the YM2164 to the MIDI channel. The FB-01 supports eight active instruments from 240 ROM Instruments or 96 user programmable RAM instruments. The FB-01 and IMFC supports sixteen MIDI channels and can assign an instrument to every channel.

But Sierra used a feature found in the IMFC which partially breaks music when played back on the FB-01.

Most of the games that have an IMFC have an IMFC driver and FB-01 driver.

M002.00.009 YAMAHA COM FB-01" for the FB-01.Īs is well-known, only PC games from Sierra using the SCI engine ever supported the IMFC as a music/sound effects device. Actually, an undocumented System Exclusive string returns "YAMAHA IBM MUSIC rel.

Essentially if the FB-01's ROM is a v1.0, the IMFC's ROM is a v2.0. While both devices only have a single 32KB Program/Firmware ROM, the IMFC has additional features in its ROM. You might think that if you emulated the IBM Music Feature's MIDI interface, you can use an FB-01 in place of an IMFC. The IMFC contains all of those chips except the LCD controller and does not have a battery. It is itself a computer with a Z80 CPU running at 4MHz, 16KB of SRAM, 32KB of Program ROM, D71051C USART, an LCD controller, the YM2164 OPP FM sound source and the YM3012 DAC. The IBM Music Feature (IMFC) was originally considered to be simply an FB-01 on an ISA card with a MIDI interface. The IBM Music Feature's Exclusive Commands The Yamaha IMFC and FB-01 is discussed here : and the Roland Sound Canvas first generation modules here : Rather than burying the information in those entries, I would like to add additional new information here. I have previously discussed both of these sound device families previous blog entries.
