Thanks for your nice feedback! :)

How many SIDs do you have going there?
only two SIDs, controlled from a single core. I think that more SIDs would just add some unwanted complexity. On the other hand, additional cores/SIDs are nice if you want to have quick and uncomplicated access to different timbres and sequences, e.g. for a break or a smooth crossover to the next tune.

Thorsten, can you please give us some more details about sound itself?
Is it just new bassline engine + feedback or there is CEMs also? My SID V1 never sounded as close as yours, probably because of the filters. :/
It's just SID + feedback.
It works with a 6582 or 8580, but not with a 6581
Filter caps: 22 nF
No external filter has been used.
Important setting: LP and BP are activated the same time, not only LP. This results into a higher resonance when audio out is feedbacked (this can even drive the filter to self-oscillation!). And the EXT flag must be set, otherwise you would only hear a distorted sound.
(Note: EXT flag is not set by default in the bassline presets, I will change this in the next release)
With MBSID V1 you are propably not able to produce similar sequences, as the V2 engine got a lot of improvements, such as:
- modulation paths are calculated with signed 24bit resolution instead of unsigned 16bit
- the filter control curve has been completely overworked (now linear with calibration functionality)
- alternative decay rate for accented sounds
- variable accent for depth parameter
- possibility to switch between sequences with a keyboard (which results into much more variations)
Some other tips:
- use analog pots, faders and/or joysticks to control CutOff/Resonance/EnvMod/Decay and Accent - they give you more direct and faster access than encoders. Encoders are fine for the remaining parameters though (especially due to the total recall capability)
- when adding drums, tune them until they are matching with the base note!
- add effects (see below)

I`m also interested what other effects are you using in your demo.
- an analog mixer to amplify the SID outputs
-> compressor
-> stereo delay (with different settings for both SIDs)
-> a stereo frequency spectrum spreader (the one which comes with Logic Audio) for the high pitched bassline
And a limiter for the mixer sum (I use the "Classic Master Limiter", which is freeware, but behaves much better than the limiter integrated into logic)

do you mind if use you demo to drop under stuff while I'm DJing?
no problem! :)
Best Regards, Thorsten.
