Back panel terminal connectors:
- headphones out
- main out + click out
- 12 separate outs
- Midi interface
- clock sync I/O
- start / stop footswitch input
- 2 cartridge slots for data and PCM.

info Power supply
standard external PSU 12V +)-



 

info TECH main core based on a 8-bits CPU Hitachi HD63B09 manages 16 voices polyphony, relative DAC is a 16 bits IC YM3014 (floating point).

STRUCTURE: each voice is assigned to a PCM sample (romple) and a pad with different parameters:
- pitch tune
- backward play
- damp (for cymbal)
- volume gain
- stereo panning.


eg rx5





info WAVETABLE
internal ROM contains 24 PCM samples at 25 kHz- 8/12 bits, split in 2 ROM banks (at IC 45/46 -about 1 megabyte).

CARTRIDGE
: more PCM can be added using the special WRC waveform cartridges models also suitable for module PTx8. Note: WRC1 is factory bundled with RX5 - Metrasound pictures from Ebay auction.

info LFO just a single modulator: it is the BEND modulation raises or lowers the pitch in 60 semitones range in a determined time speed.

info ENVELOPE
each voice features a 4-segments EG ADDR (attack decay decay 2 release) + 2 times for D1 and GATE the overall sound time, excluding the fourth release segment.
TIP a good trick for strange lo-fi sounds is the special "loop switch" mode functions.


eg




info SEQUENCER
there are 2 classic record modes:
- step grid
- real-time.
Large amount of time signature are available like 1/2 1/4 1/12 1/16 1/24 and 1/32 and various QUANTISIZE levels from 1/2 to 1/48 precision - SWING option works only in quantize time of 1/8 or 1/16 with range 50%-70%. It is of course possible to trigger sounds using MIDI protocol channel RX and TX can be set by user (Midi control by IC YM3802).

recording

 

info SYNC frequency range from 40 to 250 BPM and 3 external sync modes:
- external Midi clock
- tape sync in recorder TAPE IN.
- external analog signal: trigger with an analog signal (generally pulse wave).

info MEMORY
:
- 100 RAM patterns (up to 99 measures)
- 20 RAM songs
Memory doubled if a Yamaha RAM4 cartridge is fitted.
BATTERY REPLACEMENT: a standard 3V CR2032 soldered to mainboard.

infoEDIT there is NO RX5 editor. Anersatz retro- program is the YRM-302 RX EDITOR for MSX 8 bits computers - although it is optimized for models RX 11 / 15 / 21, it partially works on the RX5.

info MODIFICATION & MAINTENANCE



rx5 circuit  bend

Machine is quite a workhorse and requires no particular care, maybe some cleaning the pot sliders.
BENDING Due to its limit and its actual cheap price the RX series are often subject (victim?) to circuit bending experiments. This weird process creates some micro contacts in ROM chips producing strange effects and digital glitches.
