Play external samples with SID tune
There are devices for the C64 able to play sampled music without the SID.
I found the FPGASID, Sidekick and the 1541 Ultimate II to do this.
Now my idea:
Play a SID tune and mute the Percussion instruments while activating the external samples coresponding to the muted sid voices just in time.
In short: SID is playing melody and effects and the external sampler plays HiFi percussion.
Has this been done before?
I think with percussion this should be easy. With bass and bass melody more effort would be needed to pitch the sampled bass sample for different notes. Like a Amiga Tracker would do. |

It is not a big hack to grab the playing note/instrument from some random SID play routine. Then it is just the matter of getting the message to that external device to play the samples - and mix SID voices with them. I have no idea how the listed hardware actually works.
More general solution might just be to get a MIDI-interface. MIDI has been around for a while.
You should absolutely do this. |

Midi is far to much overhead and equipment to deal with at the moment. Maybe later I go for this way.
With just the C64 with two Sids, a 1541 Ultimate II and a audio mixer I have a compact setup. And it is - at least from the outside - retro.
The 1541 Ultimate can do:
- 7 independent channels
- 8 or 16 bit audio sample playback
- sample rate up to 48 kHz
- volume control per channel
- panning control per channel
- “a-b” looping
- interrupt generation

The signal of the sample player can be routed to SIDs audio in for filtering and mixing.
I am curious how this sounds.
With this my setup does not need an external audio mixer. Let´s see if this is practical. |

Some people experimented with the audio in:
