2.0.4 update


I Need YOU big time!

Let's get it straight, I got pretty quiet between summer and december 2018, reason: Piracy happened. Aftermath was at least 50% less income..and that freaked me out for a bit..this is a BIG deal for a one-man business. For years I have been offering super low access prices, I never really followed economics, taxes increase etc... while I understand piracy and the free for all concept, economic reality is what it is and I needed to adjust quickly.
I decided to request support for the 2.0.4 upgrade which will be the first and last paid update before v3.0.
While new things are in the R&D stage, past work is what feeds the actual work and I am now throwing piracy into the equation.
I am releasing publicly the last VProm 2.0.4 update for a support fee starting at 5 Euros, those who can afford to support more than the minimum are very welcome to do so.


New features in 2.0.4 are detailed below, one of them should have been implemented years ago but wasn't efficient enough at that time. 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 artifact that might happen on high frequency spectrum for high frequency heavy sound source such as for example a tambourine 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 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.

this is just one of the new features you will see bellow, I hope you enjoy making funky grooves with VPROM as much as I do!

VProm Vintage Legendary Drums VST 2.0.4 New Features Details


Powerful optional X16 oversampling keeping high frequency harmonics intact like on real hardware



Color change, closer to the original 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). Some people might have better habits with audio tapers so now you have the choice, keep in mind that default presets have been made using linear mode. The difference is Similar to this: linear will have finer detail over a small Db range of full volume, while Log can be easier for overall balance

Log Linear response


Hihat curve, timing and range updated, closer to hardware Some more advanced tests on hardware have been done to tailor the hihat VCA, timing and curve is now more accurate (new curve in RED)

Linn LM-1 Hihat


Fixed the NoDelay SNARE default Extra voice EPROM, previous one had some noise at the end. CPU usage reduced: Mainly code optimization

CHOKE action

New feature to instantly stop the playing of the Extra voice, useful for choking cymbals.. This is working only with the EXTRA voice and the CHOKE event trigger is permanently fixed to note C4, when the note is triggered it will stop the EPROM playing immediately and will be held in CHOKE until the EPROM is played again normally, the CHOKE is reflected on the EPROM playing status. You cannot assign note C4 anymore to custom MIDI mapping as it is reserved for CHOKE, if you still do, VPROM will warn you anyway :)


Voice names are now kept marked on top of the GUI panel when not in Mixer view: useful so you can actually use the tuning easily from every panel without using the tooltip naming of the tune knobs


Tune/Pan selection is now done in one click ala toggle switch: faster, better...I think :)

Version 2.0.4 is likely to be a stable update for a while so you won't be trapped in a paid upgrades forever circle. But now I also need to face piracy and will rely a lot on the user base...

The full cross-platform VProm version 2 is now available for 45 Euros, still cheap IMO for what you get: D

If you already own VProm version 2.0 (was VLinn) (including 2.0.1, 2.0.2 and 2.0.3) and have not updated yet, this full latest version 2.0.4 will only cost a 5 Euros minimum payment :)

As you probably know Aly James Lab is only me and porting my existing Windows VSTs to cross platform is taking a long time, especially while I also need to work on new developments in order to keep things interesting for everybody.
