Introducing... (sp1200 emulation)

[sinkmusic]

I listened to the demos (original and emulaiton) on the previous page, and as it is quite close, there is a little loss of dynamics and punch in the emulaiton, in my very own opinion... That SP1200 unit was loved because the quite poor definition gave more punch, and i think it is very important to keep it (if possible... !).
This is no negative comment, i appreciate a lot the work done here, just a listener's impression.

to be sure, i'd like to see the success of this thing, but i don't see how "poor definition" can produce more punch. you care to explain?

I could not make any theory about it. But i had a Akai S20 sampler (12bits/331000khz), and every time i put a sound in it, it was a more "in your face" sound than the original sound.
If sampling some kind of boomy 808 kick, the sound got a little dirtyier, and (maybe like for guitar distortion which cut some frequencies, but the sound results as heard more "powerful") also more "punchyier". The sanres were always more "snappy".
I just don't know why, but i know it worked well and i would like to find that sound again. Many plugins use "softsat" to fatten the sound, and it was that way i was hearing my samples throught my S20.

Impulse response will not do. IR can only model characteristics of linear, time-differential transofmations such as filters, EQs and room acoustics.

Bitdepth reduction is both nonlinear and static in time (it's effect only spans one sample). Muffledness is the filter characteristic of the umpulse response.

You'll be waisting CPU cycles and not getting anything, implementing a bitcrusher with some mild waveshaping both sides of bitcrusher would be a much better idea.

So wheres the site dedicated to this thing?

As for grit, here is what lionel (the sp1200 owner who so generously helped us by contributing an impulse of his machine).

But there is something that I'd like to try to explain. Although, the SP has 10 secs total of sample time, the memory is arranged in 2.5 second chunks. So this means that you can not sample anything longer than 2.5 seconds. In order to get around this, and to make the most of the total sample time, people would pitch up the sound before it is sampled, then pitch the sample down using the SP's pitch shift capabilities. This is where the real grit comes from. The SPs are actually quite clean sounding until you start pitching things down on them. I have tried to get an impulse of this effect, but the sine sweep is so distorted that the results have been unacceptable, thus far. If I ever can get that pitched impulse, I'll gladly send it to you.

VERY INTERESTING!~!!

I would like to try that also in the digital realm destructively!! See what comes out of that!

[Mike from reFX]

Easy: either a 16kHz or a 8kHz sample...

[LIMITAPROACHINGINFINITY]

Well doesnt it depend on how MUCH you tune it up or down?

[Mike from reFX]

Sure, but since you never know that you need *exactly* 3.853439 seconds, you rather pitch down by one whole octave so you have 5 seconds (16 kHz) or by two octave for 10 seconds (8 kHz). At least a sensible person would do so...

We're trying out best to preserve the original sound, thus the reason for using an impulse, obviously a bit reeducer wouldn't do the job, and we tried to keep it as close to the original for you all as possible. Your're correct that is has lost some of the high end, but I wasn't expecting (nor should anyone) an exact sound as the original. We will try to do all we can to keep the sound as close to the original as possible, this we promise!

emulation...someone's always gonna be disappointed.

will it inspire, bring on the muse, that's what will really matter!

looking fwd to this thing. how soon?

Very true indeed. We can't please them all! It is planned for release somewhere around thanksgiving, but even after it is released there may be a few things to update and a few issues (if any) to resolve.

i agree.... if this is a good creative tool... that is really what matters most. more so than being an exact emulation of the SP1200, which given the free price is not realistic. Instead, I applaud your efforts at developing this vst and look forward to its release. now on a seperate note, some commercial vst developer should take note of the demand for a virtual "sp1200 or mpc60". I would shell out a good 100-150$ if someone could do this at a commercial quality level. but again, i am really looking forward to this release. make sure and list a paypal/donation link...

Thanks, but we had planned to just inclue a readme file in it that asks you to donate to various charities (i.e. anything to go towards the katrina, tsunami, pakistani earthquae relief or any such fund or charity you feel best donating to). We are really trying to make it as good as possible. Even going so far as to inplement a sequencer. That's also being worked out still though.


We have put a lot of work into this. From creating drum sounds from scratch (as well as a few vinyl samples) to suit the original sound of the sp as well as new, more modern sounds that cover a spectrum (house,techno,etc). Then there is the work of tracking someone down with the machine in order to find an impulse and such, then there is the drum machine itself. We are doing our best to make a very good (and as close to the original) drum machine emulation as possible. Criticism is always welcome, but as was said in the very first posts of this thread. It is more "based on" than emulated. We just wanted to fill a spot in the VST world that has been left open, yet people were dying for it to be filled. Perhaps as time goes on we can perfect it and take your opinions and work together in making something very good, and yet still free. Thank you all.

Absolutely right mate! If some kits are just 'almost like' the real one we should be happy with it! Also Ill include wav-loads in order you can load own samples AND shot-sampler for each slot!

man, ive been after a decent bitcrusher for a very long time and although the emulation is not quite sp1200 sounding, its still by far the most interesting bitcrusher plugin yet. Now, i wonder, can it be used as a vsti, coloring the sound of any source in real time? This would save a lot of time for us who are used to sending samples back and forth between vintage samplers and the computer.

[dx-9]

first its a samplerVSTi, but... why not making a fx-version out of it... this can be done in a few seconds...

[reprznt]

i agree... i have an S950 sitting in my kitchen collecting dust. i have no desire to send samples back and forth to the CPU.. this software could save me a lot of trouble. thanks to the developer
