Roland D-70 pages


Welcome on the Roland D70 info pages. Here you'll find new sounds banks (PKN Sounds for D70) that you can buy and also many info about the D-70 and sound banks of other companies.

If you have some info about the D-70 that is not already on this site, or pictures of sound cards for example, please share it with me to make these info pages even better (your own pictures to avoid copyright issues). Most info is from many hours of searching on google however or my own experiences.

The D-70 is capable of making full sounding, evolving patches and benefits from the aftertouch. For it's time the synth had great power: 4 tones for an patch possible, making fat, low and interesting sounds. With four independent filters. The effect processor is an important factor of the sound. The synth isn't 16 part multitimbral, only 5 parts available, but considering the number of tones be able to play on one channel, that isn't too strange considering polyphony. Changing the patch mutes the tone.


Not a LA Synthesizer (as painted on the synth)! The D70 is not a bigger brother of the D50. On the Roland knowledge base (official Roland site) you can read this:

NOTE: The D-70 does not work with D-50 parameter cards. The D-70 uses RS-PCM sample playback as its synth engine while the D-50 uses LA synthesis technology.

Closest relation to the D-50, is that the D-70 has some sounds on board sampled from the D-50 like the Fanta Bell, Syn.Choir1 and Calliope….

With Sample playback as the synth engine, and the numbers of samples internal (internal tones 1:47, 2:44 and drums 3:28) it is to be aspected that many sounds on cards are slight variations of well known sounds. Still, with the possibility of mixing 4 tones, and some synth functions, surprising results can be made.
The D70 has 2 slots to add waveforms and expand it's sonic possibilities. All U110/U220 cards can be used, and some waveform cards were released especially for the D-70.
