These include the CS9233 Microcontroller Firmware data sheet, the
CRD9233-1 ISA Wavetable Sound Card Reference Design data sheet, the
CRD9233-3 Wavetable Synthesizer Daughtercard Reference Design data
sheet, the CS4110/CS4111 Wavetable Sample ROM data sheet, the CS4112
Wavetable Sample ROM data sheet, the CS4331 18-bit Stereo DAC data
sheet, the CS4232 Multimedia CODEC data sheet, the CS8905/CS8905A
Digital Musical Effects Processor data sheet, and an applications note
titled "A Tutorial on MIDI and Wavetable Synthesis" by Jim Heckroth.
The
CS9233 Microcontroller Firmware Data Sheet provides a description of the
functions provided in the CS9233 firmware available from Crystal. This
firmware is used in conjunction with the Crystal 1Mx8 sample ROM
(CS4112), or the 4Mx8 sample ROM set (CS4110 plus CS4111). The firmware
data sheet includes instrument lists for the 1Mx8 sample set and 4Mx8
sample set, complete MIDI implementation data, Self Test data, and
sample downloading information.
The CRD9233-1 Reference Design is a
complete ISA sound card design utilizing the CS4232, CS9233, CS4112 and
CS4331. This high performance audio adapter card includes four different
CD-ROM interfaces, and is Plug and Play configurable. The wavetable
synthesizer implementation on the CRD9233-1 features the full General
MIDI instrument set plus GS variations in sample ROM, and supports
downloadable samples with a 512Kx8 sample memory DRAM.
The CRD9233-3
Reference Design is a complete wavetable daughter card design utilizing
the CS9233, the CS4112, the CS4331, and the CS8905/CS8905A effects
processor. This design utilizes the de-facto standard WaveBlaster 26-pin
header pin-out. The high quality digital reverb and chorus effects
provided by the CS8905A are adjustable on a per-MIDI channel basis
through the CS9233 MIDI interface.
