REQ: AlyJames Lab VPROM v2.0.4 - UPDATE
This killer of a drum machine has been updated to v2.0.4.
Change Log since v2.0.3:
11/12/18 - v2.0.4
- Color change, closer to the original LM-1 hardware Darker and lighter orange
- New feature to change the mixer volume slider's response between Linear (original VST behavior) or Log Tappers (closer to hardware)
- Hihat curve, timing and range updated, closer to hardware
- Fixed the NoDelay SNARE default Extra voice EPROM, previous one had some noise at the end
- New CHOKE feature to instantly stop the playing of the Extra voice at any point, useful for choking cymbals and other creative ideas..
- Optional x16 powerful and efficient oversampling processing to get rid of any unwanted high frequency artifacts on TAMB, CAB, HIHAT and EXTRA voices (see Additional note)
- CPU usage reduced: Mainly code optimization
- Voice names are now kept marked on top of the GUI panel when not in Mixer view
- Tune/Pan selection is now done in one click ala toggle switch: faster, better.
Additional note:
When you try to emulate past technology like variable sample rate reading, one thing might be overlooked, there was no final soundcard sampling rate to begin with.
That means that any resampling artefact that might happen on high frequency spectrum for high frequency heavy sound source such as for example a tamborine will mess up the frequency content when the playing sample rate/tuning is not a perfect multiple of the soundcard actual sample rate. That crunchy sound we all like when something is played at a low sample rate is often mislabelled as aliasing...to simplify let's say there are good and bad aliasing, the good one keeps the original frequency content with additional harmonics perfectly related, the bad one will add unrelated harmonics that might or might not be desirable. On the original hardware, the bad one wasn't there and you have now the option to activate a x16 oversampling processing to get rid of any artifacts on TAMB, CAB, HIHAT and EXTRA voices, it works at any sample rate.
While most of users may not notice at first, a voice that is high frequency heavy will alias badly at 44.1K sample rate and even at 96K, it will color the sound in a way the original hardware didn't, some might like it, some don't, hence the optional switch. Once engaged the TAMB, HIHAT, CAB and EXTRA EPROMs are oversampled 16 times to get rid of most of the aliasing produced by high frequency harmonics reflection and will sound perfectly at any tune, keeping the harmonic relationship intact. Precisely it will oversample by x16 at 44.1 and 48K sample rate and by x8 above, you will have something like 768K internal processing if running at 96K, though it is kept very light on CPU! I would advice to use either TAMB, CAB, HIHAT or EXTRA PROM slots to load any high freq heavy custom EPROMS, they will sound better oversampled at least if you want no nasty coloration, just test on the tambourine and you will hear it.
