RGB4 … Come and get it..

Posted in krakli on August 31, 2009 by krakli

I was in a quandary here, I have had RGB4 waiting in the wings for quite some while, but it appears to have confounded most of the guys that have volunteered to write patches for it, with a couple of exceptions..Thank you Heiko!

I couldn’t keep holding back and for one reason or another I wasn’t able to spend my own time patching it so I thought I would try something a little different. I haven’t put it up on the Free Synths page as I consider it in beta, but you can download RGB4 HERE. At the moment it only contains 22 of the 64 patch slots filled, but hopefully some of you out there might be able to add to that number.


It has a very unconventional architecture, and I will probably need to do a manual or video tutorial so that you can best understand it but let me have a quick stab at breaking it down.

It consists of two main sound sources: a 32 partial additive Osc and a more conventional  multi-wave VA Osc.

The individual levels of each partial can be controlled by the red sliders at the top left of the display, or by the ADSR sliders ranked below each partial. Obviously if the Red sliders are all the way down then ADSR sliders come into play but only if the blue sliders are above zero, these blue sliders vary the amount of ADSR modulation.

The Green Oscilloscope trace shows the realtime modulation of the waveform.

Below the Additive partial controls is the Multiwave Oscillator, this should be familiar as the Oscillator from the S3 series and has a few simple controls and a mix knob to vary the amount it comes into the sound.

The multiwave waveform is indicated by the Yellow Osscilascope display.

On the right hand side of the interface are a global ADSR which affect the overal amplitude of the sound, below these are Octave Velocity and Volume amounts, below these are controls for bend range, and controls for vibrato, delay rate and amount.


The next section below this is the filter modulation section.

The coloured block with the cross hairs is an x-y pad which is activated by clicking on the background area. If it is on it overrides the middle four filter frequency controls. If it is off the 6 filter frequency controls become active. these are lo-pass 4 band pass and hi pass filters. and it is the use of the 4 band pass filters which help RGB4 to achieve some of the more vocally patches that are included. the resonance controls are below this and then an envelope modulation slider for each filter. Below this are contols for the LFO waveform and amount.

The global control for filter LFO rate is beside the x-y pad and very slow settings with the random LFO waveform result in an interesting effect! The grey/red slider to the left of the rate knob shifts the phase of the LFO waveforms so that a more varied sound can be achieved.

As I say a very quick run through of the RGB4 controls and it will be interesting to see what you clever people make of it. If it is at all successful I will release the plug-in properly.

The stuff wot is going on….

I thought it might be useful to take a breath and mention what is happening in the world of Krakli at the moment, and also set a little bit of a puzzle!
Firstly I had previously posted Morhiza2

 which you can find on the Free Synths page. TBH this is absolutely a re-coloured version of a plug-in that was previously part of a magazine special. I release it now as the magazine has moved on and also because some interest was shown in transistor organ plugins.

Next up is the activity around RMXL: As you can see in the previous posting Dimitri has been kind enough to provide 2 new banks of 128 sounds for RMXL. In my opinion there are some real gems within the banks, and they really add to the fantastic work done by himalaya.

Also I have gone on a bit of a detour and to all extents completed RMP2

You may recall that I said that the S series and later RM series synths were born out of some of the ideas in the original RMP. RMP2 has effectively come full circle, and what we have here is one half of RMXL combined with the S3 synth. However each synth can be thought of as an independent instrument each with its own arpeggiator and FX section. You can zone the range of the instrument with the keysplit control at the bottom.
Certainly this version acheives the flavour of the original but because it is much simpler (without all of the GUI customisation features of the original) it is running without a hitch.
Due to the fact that it still carries the SE multi-core bug I won’t comfortable selling this at a fixed price, but I may look into offering it as Donationware, possibly replacing S3Ks in the bundle that is currently offered.

… And finally the puzzle.

As you are most likely aware there is quite a number of synths available on the Free Synths page. Some of these have been there for a while, others are much newer.  Now, I can track the downloads of these and I sometimes take a look at what is being downloaded on a daily basis. This normally shows a bias towards whatever the ‘newest’ or most poular things are, so for example, atm RMXL and Morphiza2 are getting lots of downloads, but Cygnus is always high up in the numbers. However just recently I have noticed one of my more ancient plug-ins is nestling in amongst the top 5.. and the question is, can you guess which one is getting all of the interest at the moment. The answer may suprise you!

RMXL – 384 and counting!!!!

Dimitri Schkoda has done it again..

A further bank of 128 presets dropped into my inbox this morning. Including the 128 originals from himalaya, this now means that there are 384 RMXL presets to choose from. Dimitri was kind enough to say:

Ok ! I definitively love this beast !!!
These soundbanks are made to tell that each preset can become a whole story in itself !

I have added here the links to this new bank and also the previous bank that Dimitri provided:

Dimitri Bank 1

Dimitri Bank 2

Plus as a further bit of RMXL news. K-Bee discovered RMXL enquiring about free physical modelling synths on KVR. Trying RMXL out upon recommendation he came up with this very nice little track:


K-Bee said that RMXL inspired him to produce music that was different from his normal stuff. In this case he was using 3 instances of RMXL and he has suggested that he will now go on to use RMXL in further creations. Apparently he has also just discovered StringZ2 but he has said that he is finding that one a little harder to tame !!!

I am really encouraged to see all the interest that RMXL is causing in certain quarters. The RM type of instruments remain my personal favorites and it is great to see others enjoying them.

Speaking of RM? …

 This youtube clip shows that I am busy working on RMP2. A version of RMP that will definitely make it to the web-site this time.  I have adopted a more realistic approach as to what can be acheived and yet this version has most of the major features of the original RMP. It is early days yet but I will most likely make this one donation-ware, perhaps with a minimum donation amount so that I don’t get stung for paypal charges.
