Amiga cartridge ?

[ssirkriss]

Hi,

I am interested in making Amiga sounds. I never owned an Amiga. I just like how Amiga chiptunes sound.
Is there possibility of an Amiga cartridge in the future ?

I guess not. The Amiga 'soundchips' are very different than soundchips from old homecomputers. Many Amiga music is being made with trackers which work sample based.

There are lots of the "paula" amiga sound chips on ebay .

I'm no engineer though.

Resurrecting an old post. This also depends on what you mean by Chiptune on the Amiga.

'Full size' modules were not called Chiptune back then. What I mean is that any tune which, aside from drums, had samples that were larger than a very short looping waveforms were considered 'Full sized'. Chiptune on the Amiga, which is where the term/phrase/style Chiptune originally came from - no matter what people say these days, used mainly single cycle waveform loops and were usually under 30kb including the pattern data.

If you're talking (real) Chiptune, then the samples didn't sound noticeably unique when pitched up of down. The Amiga did, however, have two built in low pass filters, one of which was switchable which NerdSEQ won't. The larger 8 bit samples did sound "Amiga" due to the sound chip changing the sample playback rate to change the pitch of the sample, instead of resampling it. I don't know which way NerdSEQ does it, but that would be my guess.

The nerdSEQ does not change the playback rate for a pitch change, it always stays 44.1kHz. I expect also even though if it would change the samplerate then it wouldn't sound exactly like the Amiga either. The character is defined by the DACs, jitter, pre-conversion of the samples, Post filtering etc. 
The NerdSEQ tries to reproduce samples in the best possible way within its own limitations. 
External Cartridges have been an idea back in the early NerdSEQ days (derived from the Nerdsynth which was a standalone tracker 'groovebox' long before the NerdSEQ. It never made it into a product since the NerdSEQ took over). But the Cartridge idea (which would involve dedicated synthesizers mostly based on old soundchips. They exist, they have been used for the Nerdsynth and NerdSEQ in the early days) was eventually dropped since it didn't really fit the NerdSEQ ecosystem anymore.
