Re: Xaoc Batumi + Poti 2016 batch

Just for clarification - all factory units come with jumpers installed on their pins. They are tested with these jumpers and it's unlikely somebody would buy a brand new Batumi without jumpers. Customers take them off e.g. to connect a Poti, and sometimes forget to put them back when selling the uni...

Re: Xaoc Devices Timiszoara: Voltage Controlled DSP Effektor

For the record, Timiszoara is based on a single Spin FV-1 chip. All dual programs will inevitably share the resources, just like in any other effect pedal or module of this kind.

Re: Xaoc Batumi + Poti 2016 batch

Hmm ... apparently not. You just dismantled the pin header by taking off the plastic piece that keeps pins together. Please use a real jumper, this thing obviously does not offer any conductivity.

There is no such thing. Are you sure you know what a jumper is?

Re: Xaoc Odessa, 1975 Variable Spectrum Harmonic Cluster VCO

This must have been some misunderstanding. Of course, this is paraphonic voicing with fixed polyphony, and inputs on Hel are 12TET quantized, hence there are limitations. Customers sometimes enquire with some inacurate preconceptions in mind, and we need to rectify them. But we never meant to sugges...

Re: XAOC Devices - Praga

There is a confusion here. Muting is implemented via VCAs. However, the "VCA out" jacks are using separate mono VCAs, they are not the same as main mixing stereo VCAs that are going to the stereo bus. Please see the diagram in the manual. Please note that the Aux sends are also taken from these addi...

Re: Xaoc Odessa, 1975 Variable Spectrum Harmonic Cluster VCO

FYI, the LinFM slider has a hyper-exponential response (unlike the other sliders) which was necessary to allow setting either very shallow and very deep modulation depth. The LED shows only the AC part of the signal because this input is AC coupled. It also has different scaling because of the slide...

While we did encourage customers to build their own DIY Poti versions, we strongly advise against making a DIY version of Nin.

Re: Limiter (or clipper) for CV?

Samara II offers this as well, both limits are voltage controlled, and they don't have to be of opposite polarities (eg. you can clip your waveform between 1V and 5V if you need that). Also, it can perform this in two parallel channels, as well as plenty of other waveform processing functions.

Re: stereo mixer module comparison

There are no capacitors in signal path in Praga, it is DC coupled. Hence, there are no means that would introduce any delay to the audio signal, and there is no phase shift. There must be something else that you take for phase shift. One common mistake with an oscilloscope is to forget that changing...

Re: Xaoc Zadar, Quadruple Envelope Generator + Nin expander

There is advanced debouncing already implemented in Zadar. The problem is, acceleration and debouncing are somewhat contradictory. The more acceleration we allow, the more it is sensitive to encoder wear. Without acceleration turning dials in Zadar would be unbearable, hence some compromise was nece...

Can Jena and Lipsk be connected/used with Odessa without the Dresna module? Yes (partially). Lipsk alone works very well with Odessa allowing to switch individual partials or sequences of partials within banks on and off, both manually and by using its 8 gate inputs. Jena needs some input digital d...

Re: Xaoc Odessa, 1975 Variable Spectrum Harmonic Cluster VCO

We are sorry, but the request to automatically exclude the fundamental from the main outputs once the fundamental is patched out is completely unrealistic as it seems to presume the components are generated separately and mixed only at the output jack. They are not. These signals arrive from the fpg...

Please, do not forget that Odessa is an oscillator rather than a complete synth voice and it is supposed to be processed by other modules, like filters.
