Hi all.
Has anyone out there had any experience with building a transient designer type plug in like the SPL transient designer? Or similar?
Its mainly for a drum sampler I have been working on for use in my work and music production. I find transient shaping is more effective than traditional compression in a lot of cases for Drums.
I have been banging my head against the wall with this. Been over to the yahoo group but still I can't seem to get the help I need..
A transient shaper is able to adjust just the attack portion of sounds and the release. The overall effect is similar to compression.
I managed to have a look at the schematic of the original SPL machine but it doesn't show the actual detection circuit or the Vca control circuit. But further investigation shows it works off of something called a differential envelope. For example. For the attack stage it's uses 2 envelopes. 1 tracks the program level and Env 2 does the same with a longer attack time. Now when 1 envelope is subtracted from the other you are left with just the initial attack transients. These transients can now be made louder or quieter.
the release works in a similar fashion as far as i can make out.
I have tinkered around endlessly and it's so hard to find non technical information on the subject. I can find out how to build almost anything else in synthedit but not this...
Chris kindly gave me some advice for the detector part. I have tried this and I'm not sure it's working.
You should use 2 CK_Metering modules. One to Track the Programme Level and one to track Peaks - subtract the Programme from the Peak gives you an Over/Under transient impulse. Clip it to 0v to only respond to Over Transients.
For the Peak Metering - use CK_Stereo_Peak_Hold -> CK_Metering & set the peak hold time accordingly so your system can respond to them (typ 10ms)
For Programme Metering you should typically have Atk/Dcy around 200-300ms.
apparently this will give you the Transient impulse signal - this allows you to identify when an over/under transient occurs and its level/shape (above the average volume)
Then a way is needed to use that signal to effect the main audio and I think that's where the differential envelops comes in..
If anyone out there could be kind enough to help me with this I'd be very appreciative.. I can't seem to find anyone that's made one with synthedit.. A few examples on other platforms like pd, reaktor etc but nothing for synth edit.
A couple over in the yahoo group hinted this was a trivial task and I do feel kind of stupid as I'm going around circles. I've managed to achieve so much with synthedit but this has got me Stumped..
Thanks all... Anything will be helpful
