features and uses
Main Features
•
extremely low-latency system response time similar to equivalent dedicated outboard hardware
•
programmable midi input processor allowing for 144 complete midi message operations in real-
time, via a total of 432 conditional verifiers and 576 data transforms
•
2 channels of audio input, each with 2 additional filter channels for a total of 6 independent sources
for audio to midi conversion; each channel is equipped with individual conversion modes, filters,
gates, gain settings, intelligent data thinning algorithms (for continuous controller conversion), and
arithmetic processors
•
audio channels can be configured as a six-band filter bank for complex spectral based audio to
midi conversion
•
selectable filter types for each audio channel including shelving, band pass, and peaking EQ, all
with individual frequency and Q
•
2 channels of ultra-fast spectral analysis with bandwidth activity analysis to assist in assigning audio
filter parameters for audio to midi conversion applications
•
audio can be converted to midi in both trigger/gate as well as continuous controller modes
(functions like an envelope follower)
•
fully programmable gameport and mouse to midi conversion providing 12 additional channels of
variable and binary midi control, allowing for the design and implementation of custom midi control
surfaces
•
midi clock generator with tap tempo, quick control keys, programmable auto-sync’ed midi click
track generation, and optional visual tempo cue source using the computer keyboards’ LEDs
•
8 clock-synchronizable lfo generators with a variety of programmable waveshapes, to generate midi
continuous controller streams or used as modulation sources for the midi input processor
•
highly configurable user interface and real-time performance load – converter can be adapted to
perform well on any machine from a 486DX/33 to a Pentium 233MMX and beyond
•
supports a variety of laptops for portability in live performance situations
•
costs almost nothing for the type of hardware required to operate converter
•
very stable – can operate indefinitely without requiring a reboot
Uses
•
add additional controller functionality or midi data support to equipment with limited controller
programmability or primitive midi interfaces (such as vintage midi synthesizers and drum machines,
drum pads, stage lighting controllers, effects processors, etc.)
•
clock-synchronized low frequency oscillators can add synchronized sound-shaping features to
classic synthesizers – useful in sequencing environments
•
convert certain system exclusive messages in real-time; translate from one format to another
•
provides new possibilities in sampling by providing a new type of envelope follower, allowing one
sound to adopt various rhythmic or dynamic inflections of another sound in real-time (as a basic
example, impose a rhythmic pulse to a filter on a sound on a synthesizer, based on a drum loop
passed into the audio input in converter)
•
enables sounds on an external midi device to be triggered from audio input peaks, for example a
mic’d snare drum could trigger a sampled snare sound etc.
•
provides quick and easy master midi clock for a midi setup in a live performance application or
creative studio environment, with the ability to provide reference tempo cues for human performers
•
trigger sound, lighting, or other events from objects on a stage in a live theatrical, musical, or new
media performance
•
provides a useful tool for debugging or testing midi systems / implementations
