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.

eg info TIP a good trick for strange lo-fi sounds is the special "loop switch" mode functions demo HEAR keyswitch






info SEQUENCER
there are 2 classic record modes:
- step grid
- real-time

recording

Some sequencer main functions:

-SIGNATURE variable time signature are available: 1/2 1/4 1/12 1/16 1/24 and 1/32
-
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%.





info SYNC
frequency range from 40 to 250 BPM and 3 external sync modes:

sync - external Midi clock
- tape sync in recorder TAPE IN.
- external analog signal: trigger with an analog signal (generally pulse wave).


 

info MIDI it is possible to trigger sounds using MIDI protocol channel RX and TX can be set by user (Midi control by IC YM3802).

 



info MEMORY
:

motherboard rx5

- 100 RAM patterns (up to 99 measures)
- 20 RAM songs
Memory doubled if a Yamaha RAM4 cartridge is fitted.

info LEFT - BATTERY REPLACEMENT: a standard 3V CR2032 soldered to mainboard. -Click to magnify PIC -



 

infoEDIT there is NO offical RX5 editor.

rx5 msx editr

info A hard to find 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

RX5 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

info DISCLAMER WARNING: DO NOT PUT A SCREWDRIVER AT RANDOM INTO THE MACHINE (LIKE I DO) THIS IS DANGEROUS -- bla bla --
