Roland SDE-330
Dimensional Space Delay (1993)

 

Digital delay with pitchshifting engine plus special tridimensional acoustic Roland RSS system.

RACKMOUNT 1 unit. Main panel features a double display, 12 buttons, led peak meter, 1 rotary data encoder and 2 knobs.


Back panel terminal connectors:
- Midi interface
- main signal out
- signal input +4dBu / -20dBV
- bypass pedalswitch input
- control pedalswitch input selects a parameter to edit
- expression pedal input.

 

 

 

VOICE main core engine is based on a 16 bits CPU NEC up-D70433 signal is processed at linear 16 bits / 44 kHz which handles 19 algorithm effect processors.
The DAC / ADC is an Asashi Kasei AK4501.

 

 

EDIT INTERFACE quite clear and logical, not to much to tweak like most of the nineties production.

 

EFFECTS all sound patches are based on 19 algorithms by custom DSP model TC6088AD.

 

Simple 3D Delay standard delay up to 2,8 seconds with RSS 3D effect+ modulation LFO (from 0,1 to 10 HZ shapes sinewave /triangle) + final EQ. Input channels are mixed to a single one. Simple Delay same as above without RSS process. Stereo 3D Delay standard delay up to 2,8 seconds time with RSS 3D, modulation LFO (from 0,1 to 10 HZ shapes sinewave /triangle) + final EQ. Inputs 1 + 2 are individually processed. Stereo Delay same as above without RSS process. 8 Tap 3D Delay multitap delay (up to 8 echoes at the same time) with RSS + 3 bbhands EQ. Input channels are mixed to a single one. 8 Tap Delay same as above without RSS process. Quad 3D Delay 4 serial delay engines: it's a multitap delay up to 4 echoes with RSS and stereo pan position. Quad Delay same as above without RSS process. Duck 3D Delay sidechain delay (VCA EG) with RSS 3d. Duck Delay same as above without RSS. 4 Pitch Shift Delay 4 taps delays + 4 serial pitch shifter engines + 3 bands EQ. Reverse 3D Delay backward echoes with RSS azimuth + 3 bands EQ. Reverse Delay same as above without RSS. Mono 3D Non Linear gated monophonic reverb with RSS technology. Mono Non Linear same as above without RSS. Stereo 3D Non Linear gated stereophonic reverb with RSS technology. Stereo Non Linear same as above without RSS. Precision Delay 2-taps delay + 3 bands EQ.

MIDI a selected parameter con be controlled using CC# or note triggering in case of a keyboard, in addition it is possible to change the effect number using the program change Midi function.

 

 

MEMORY:
- 100 ROM patches
- 200 RAM patches.
Memory can be saved to Midi sysex dump.
Battery replacement: standard CR-2032 battery in holder, no soldering.

 

 

MAINTENANCE I just had to change some tact switches that were getting hard to push.

tact switch failure!	.. and replacement

 

 

RELATED FAMILY:

	SDX-330- same series, very similar circuit but dedicated modulation.
	SRV-330 dedicated to RSS reverbs.
