A113

2015-11-25 by David Kellett

Hi - can anyone tell me what the Peak to Peak on the single outa of an A113 is? I'm trying to do something with the single outs that is not working as expected. I'm putting them into FM Aids to convert to sine waves for a special application but the FM Aids do not seem to be doing this as expected. FM Aids work very well changing A110 Saws to Sines (also Rubicons, Z3000s). So I'm wondering what is different about the A113 outs. 

The A113 is a new one - no 5v needed.

Hi David,

One thing that springs to mind (and mind you, I don't own an A113!) is that it might have to do with the direction the saw wave moves. I notice a difference when using ascending or descending saw waves wave.

I'm just guessing here...

Good luck!

The Saws look, on an oscilloscope, to be the usual way round - virtually instant stack and then a fall. I don't know how to tell if they have a DC offset or what the VPP is. I'm ok with listening and a very cursory look at the oscilloscope but not very electronically literate beyond that.

Looking at the oscilloscope some more - I think the A113 are maybe not as loud and not as sharp edged as other oscillators. The slope seems to be slightly "bendy" and the rise is maybe very slightly less fast. 

I guess my idea is not going to work quite as I had envisaged. I had hoped to get quite pure sines from the A113 single outs going through the FM Aids and then using them to Phase distort the WMD PDO's 3 channels. The basic frequency of the PDO being a chef with division 24 on the A113 and then all the sines therefore being whole number ratio multiples of the base frequency - so 18 being a 4:3 ratio and 16 being 2:3 (a perfect fifth) - and also being in phase. 

I have rather an amazing drone going on here anyhow with the "not so siney sines modulating the PDO and themselves being self modulated and folded with all amounts being slowly modulated by LFOs. Lots of weird harmonics drifting around.

The single output levels are about 4Vpp. But the waveforms are far away from a perfect sawtooth as the A-113 circuit tries to
simulate the waveform of the original trautonium oscillator which was also no a perfect sawtooth. If the converter expects a
standard sawtooth it will not work.

Hi!

The A-113 was one of the first modules that I ever bought and I still use it regularly to this day, in my opinion it is very overlooked.

Here is an unashamed spam/plug of one of my patches using it.

Thanks for the info Dieter. It may be that I get "better" sines by adjusting the FM Aids as they expect 5V point to point. What I'm getting at the moment are some very odd looking shapes :-) They sound rather interesting but not what I needed for this patch to work. 

Thanks again,

David

I have watched your video when I was researching the A113. Good video. 

Yes the A113 has lots of potential - doing Trautonium type things is just the tip of the iceberg. That is what is so interesting about Modular stuff - you can repurpose nearly everything to make something different with it.
