based on E-Mu System's Proteus 1 MIDI Sound Engine
it's an independent computer with a 68000 @ 10MHz
128 kB Operating System ROM
64 kB static RAM
4 MB of 16 bit General MIDI samples in ROM, over 210 sampled sounds and waveforms
a large number of configurable parameters allow a lot of flexibility in the sound: velocity control, pitch bend, adjustable tuning, and a choice of scale temperament
no built in effects (they are produced by software)
16 bit sampled stereo synth which is both polyphonic and polytimbral, so multiple instruments can be played simultaneously, up to its limit of 32 internal channels
some instruments need multiple internal channels
the Proteus is mounted as a daughterboard and interfaced to the Amiga via one port of a DUART
the other DUART port provides a built in MIDI interface
1x MIDI In
1x MIDI Out
expandable to three separate MIDI outs with the optional Triple Play Plus upgrade
stereo output (two RCA plugs)
bundled with Bars & Pipes Pro, supported by SoundJam
when the editor is first started, it has to read the entire configuration from the hardware, which takes about 20 seconds
works together with the Sunrize series: using Blue Ribbon's SyncPro (SMPTE Generator), both the AD1012 or AD516 and B&P Pro will lock to SMPTE, independently
two channel simultaneous playback (simple stereo signal)
unlike a DSP, this chip is designed solely for handling audio, it cannot for example, off-load your CPU when playing back an 8+ channel ScreamTracker file
connectors
LINE
can be routed to the ADC and to the onboard mixer
normally used for recording line level signals
MIC
can only be routed to the ADC, not to the mixer
used for recording only - signal may be line or mic level
AUX1
can be routed to the ADC and the onboard mixer
used for recording or mixing the audio output of a CD-ROM drive or the MPEGit MPEG audio decoder expansion module
AUX2
can only be routed to the mixer - cannot be used for recording
recommended for mixing with the Amiga output
after a reset when the card is not initialized by the mixer program, LINE out is muted and the source connected to AUX2 can only be sent to the mono output
OUT
goes to stereo system
notes
15 pin D-SUB connector for the customizable adaptor - when ordering, the type of connector can be chosen for each input (e.g. RCA, 1/4" phone plug , 1/8" phone plug
mixing means that the signal of that input can be mixed to the output along with other inputs, and the sound generated by the codec itself
recording means direct recording to RAM or hard disk from that input and also using it for digital realtime effects
40 pin (male) expansion bus connector for expansion modules
MPEG-it! - MPEG audio decoder supporting Layer II & III streams
Arpeggiator - digital input / output (S/P-DIF) for DAT, CD, MiniDisc, etc.
full duplex 16 bit audio sampling, mixing and playback
sampling and playback rates up to 64 kHz even on 68000
EMI filtering and double surge protection
