■ Rz1 is based on a custom NEC uPD7811 8-bit microcomputer. It's quite a strange machine, with 12 sampled sounds , a sequencer and 4 pads for sampling quite similar to previous cult machine Emu SP12. It's mainly plastic with a 16 character backlit LCD and a mixer section.
■ SAMPLING Sampling on the Casio is a very simple process to initiate. Hold down the Sample button and Sample 1 together, then feed a sound into the sample input to trigger the sampler. The display flashes SampleOK! you have a tiny for 0.8 seconds time (TOTAL!) Each sample length is limited 0.2 seconds, and if you want to increase this you simply hold down Sample 1 and Sample 2 for a 0.4 second sample, or Sample 1 and Sample 4 for a whole 0.8 second sample! wow
■SOUNDS The RZ-1 comes with 12 factory drum sounds at 8 bits (bass drum, snare, open and closed hi-hat, clap, cowbell, ride, crash, and three toms), its' very very lo-fi sound.
■EDIT Sound cannot be really edited but volume with internal handy mixer or 'Accent' and 'Mute' three levels of dynamic are possible for every sound. Samples also cannot be much edited but some kind of low pass filter on the rear (kind of trimmer).
NOTE: The alternative non official OS includes a special sample reverse mode and a kind of attack trim.
■SEQUENCER realtime or step recording with 1 to 99 bars, but a 99 bar, with variable time signatur and the quantisation can be set to any value between half-notes ) and 1/96 notes . Patterns can also be copied to other locations, or deleted. Song' mode gives access to 20 chain slot , each of which can contain 99 steps. 'Edit' allows a different pattern to be entered at each step, or an existing pattern to be replaced by another. Using the yes/no buttons as wind/rewind, any individual step can be quickly located and played back
■SYNC only Midi, note that sound can be also triggered by Midi also.
■MEMORY you can save the patterns with external tape mode (8 dins or simpler midi dump)
