Koshdukai's Music(al) Reason(ing)

Record users may already know this trick for quite some time :) You can record CV data to an audio track through the use of a CV to Audio converter (like the CV2Audio2CV ) to then examine the CV waveform. This is useful when we need to debug or check the CV values being generated by a device. The only problem with this, is that if we're on a long tweaking session, the CV recording (i.e. CV "log") may get pretty big unnecessarily. One solution is to go on a sequence of short recordings, while deleting the resulting Audio Track clips in between those sessions. But now there's Reason 5 and it's new Sampling capabilities that we can use also for CV monitoring. So, now, instead of recording to a track, we can just Sample the CV, again through the use of a CV to Audio conversion (wiring the audio output of Thor to the Sampling input at the back of the rack, making it the sampling source). This allows us to keep an eye on the thumbnail Sampling scope window, while doin...

Sorry, but I only have time to show what's possible to do with some of the available rack devices, to show the CV values, like I mentioned in my previous post. It also shows one possible version of the CV Scope, using the CV Delay and CV2Audio2CV :) As soon as I have the time, I'll explain in detail how to achieve each of those unusual device uses. It's quite simple, as many will quickly figure out. Some of you may already use something similar to do your CV debugging, like I do.

A "CV Delay" is quite easy to do once you have a way to convert CV to Audio and Audio to CV (you can use the CV2Audio2CV for that). A simple way to achieve this with up to 4 independent CV signals, is to use Thor's Audio outputs connected to 4 DDL-1's and back again through Thor's Audio inputs: (click to zoom) So, to test all 4 CV delayed signals, I'll use BV512's CV inputs to graphically show what's going on: (click to zoom) Now, let's check the front and see if the CV Delay is working... (click to zoom) ...and there you have it, a working 4x CV Delay:) Next post I'll talk about some of the devices and the way I usually use them for CV display (more like CV debugging, really). I'll talk about the use of the DDL-1, MClass Equalizer, RV7000, BV512, Thor and PEQ-2 as possible CV debugging tools. After that, the obvious way to do a rudimentary CV Scope using a stack of 4 CV Delay units :) ...as you can guess from the above pictures, it's ...

I guess it's common knowledge that Thor is much more than a very powerful synth :) Besides being a very powerful versatile multi-filter+effects device, it's also a very capable CV machine, capable of very cool and useful CV processing and generation. I have many basic patches at hand that I use as basic building blocks to build more complex combinators. Some I've already mentioned here, but many others I keep to myself because there are already equivalent devices made by others before me, or some are so basic (although useful) that I think it would be kind of weird to mention them here. Recent events lead me to change this idea a bit. I'm beginning to realize that what some may consider as basic knowledge, it may be news to others, so why not make some quick posts about it ? So, this post will quickly show a very useful use of Thor's modulation matrix and input'n'outputs at the back. This little patch deals with CV to Audio and Audio to CV: (click to zoom) S...
