KORG volca keys random patch generator

VOLCA RANDOM PATCH is a little experiment in me learning javascript and CSS and application of WebMIDI standard in a simple webapp for creating random patch data for KORG volca keys.

It is a work in progress, but from version 0.1 its functional and a lot of fun if you have a volca keys some midiinterface and a web browser that supports the WebMIDI standard (Chrome is the best, on iOS I have successfully tested the free Web MIDI Browser).

There is an updated version 1.0 with more functionality for anyone to try.


Primal Audio FM4 and Yamaha TX81Z preset matching

Some say that Primal Audio FM4 synth for iOS platform is a recreation of Yamaha TX81Z FM sound module in a modern form. The app alone is promising. I miss effects because my “old” iPAD 3 with A5 processor cannot handle using another effects app trough Inter App Audio without glitches with 8 note polyphony. But when I saw a few vids on youtube of the original TX81Z what I really missed was the ability to import original syx patches. This is not possible right now and I don’t see the possibility in a near future also. This is due to the slightly different structure of the synth and the app. The envelopes which are crucial in FM synthesis have different parameters, operators also are a bit slimmed down.

So if you were hoping for a quick fix converter of patches I have bad news. But I have managed to recreate a few presets by observing the settings in an Yamaha TX81Z editor software that can load (not play) original syx patches even without the device itself. A lot of people will want the Lately Bass. So this is my take on this classic FM patch with the lovely FM4 synth by Primal Audio. I have a lot more and will post these later as a whole bank.

To try the patches you have to download the zip archive, unzip to your computer and import the files trough iTunes to your FM4 app. Enjoy.

Korg Electribe EM1

korgelectribeem11This is one of the Korg grooveboxes with very usable internal sound set for bass/lead/instrument sounds and good set of drum samples. The drumsamples have been around the web and can be found for example here.

The bass/lead/instruments samples have never appeared or I haven’t found them and so here are some of them in SFZ format to have a taste of how this box sounds like. Some of the waveforms were probably on a CD that was shipped with the newer Electribe ESX units.

Of coarse this is only a bare sound looped and mapped over the keyboard. The filter sound depends on the sampler instrument you are using. Also effects section is missing so you have to use something similar from your vst toolbox. For now there is no control over the Amp envelope but since I’m using sforzando sfz player on my Mac I plan to implement controls for this as well for the filter in the future. So if you’re interested stay tuned or comment.

I have sampled the whole sound set of this instrument and plan to release a full SFZ library. Since it is a time consuming project I would appreciate some feedback on this just to know that someone will be interested. Thanks
