Chipflip: Realtime SID delay

News of a cool new technique for actual delay(as opposed to a software effecting using spare voices)  that runs exclusively on the older 6581 sounds chip.

He explains:

The Norwegian composer Geir Tjelta has introduced a new trick for the SID-chip: realtime delay. The output of the third channel of the SID can be recorded, and by delaying the playback of the sample on the “virtual” fourth channel, you get a subtle echo. This routine doesn’t use much CPU-time either. A nice and elegant trick. Get the exe and mp3 here.

He then teases the following:

Geir also programs an editor together with GRG, Sid Duzz It, which according to the rumours will include this echo effect along with extensive MIDI support in the next version.
