Main Features
Both a MIDI sound generator and an audio interface
The SC-D70 provides a complete platform for desktop music production with MIDI 
and audio. It allows you to create sequence data that combines MIDI and audio, and 
allows MIDI → audio conversion by looping back the output of the sound 
generator—all by connecting a single USB cable.
24-bit/48 kHz USB audio interface
An original Roland driver and custom IC are used to support 24-bit/48 kHz USB 
audio. ASIO  1.0  is also supported, allowing songs with audio tracks to be created 
using numerous sequencer programs.
Digital audio I/O
The SC-D70 provides digital audio I/O. By connecting it with external digital audio 
devices such as CD or MD, the output of the song you create can be converted into 
digital form. Both optical and coaxial connectors are provided.
GM (General MIDI)/GM 2 (General MIDI 2)/GS format support
The SC-D70 supports the GM, GM2, and GS formats. Music data conforming to the 
GM/GM2/GS formats can be played by a computer or sequencer on the SC-D70.
32-part/64-voice sound generator
The SC-D70 contains a 32-part, 64-voice multitimbral sound generator. You can 
enjoy ensemble performance using just a single SC-D70.
* Only when the USB connector is used. When the MIDI connectors are used, a maximum of 
16 parts are available.
Versatile and high-quality sounds
The SC-D70 provides a versatile and high-quality selection of 1,608 sounds and 63 
drum sets. These include the same sounds as the SC-55/55mkII, SC-88, SC-88Pro, 
and SC-8820, allowing you to enjoy your existing music data or commercially 
available music data.  (*1) 
Furthermore, the sounds that are available on the SC-8820 tone map are organized 
in a manner that is compatible with the top-of-the-line SC-8850. This means that 
music data that was produced for the SC-8850 can be played back using essentially 
the same instrumentation (*2).
*1  The performance may differ slightly depending on the data.
*2  Although the arrangement of sounds in the SC-8850 map and the SC-8820 map are 
identical, differences in the waveform data that is used, the number of voices used by each 
sound, and the maximum polyphony of each device may mean that the reproduction may 
not be perfect.
A full complement of effects
The SC-D70 provides 64 different insertion effects, 8 kinds of reverb, 8 kinds of 
chorus, 10 kinds of delay, and a two-band equalizer. In addition, you can adjust the 
parameter settings of each effect for total control over your sound.
