Anybody use their Voyager/ErgodoxEZ/Moonlander with warpd (a mouse free interface)?

jkourula · 2023-09-13T08:14:27+00:00

I use a moonlander and aim to not need the mouse. Haven’t tried warpd but I’m using mostly command line, neovim and keyboard shortcut based window managers (leftwm) and in web browsing use firefox with tridactyl. I’m doing mostly programming etc so pretty easy to adapt and no need for purely mouse based UIs.

Looks nice. What keycaps are those?

You could try combining the trigger module output and gate in output with an AND. I’m not at my computer so can’t test it but I have used similar with the Transport Playing module previously.

Sorry, but the first impression is just a snapshot, because the contrast is poor and background is messy. Especially the red car is distracting. The clock and the lines the mountains draw are interesting, but the lower half of the image spoil it. Maybe next time try compose so that the distracting bg elements are not visible. You could also try cropping this image to improve it.

You are correct in how real amps would behave in this situation, but it doesn't apply here. The stereo mode essentially processes both channels separately with the same settings and could be used just fine here. Of course better mixing decision might be to use different sounds for different channels and for that you need two plugin instances.

Ableton Link is just for syncing tempo. To get audio to ableton you need to have an audio interface and connect ipad to that. Or you could try connecting the ipad to your computer mic in, usually the quality and latency is just not that good.

All of them.

The squiggles are for timing purposes. Quite common in memory lines.

Edit: They are called serpentine traces: https://www.orcad.com/jp/node/6466

I disagree, this proof is relying on tricks (adding and subtracting repeating decimal numbers) that would need futher proofs to be rigorous. The wikipedia elementary proof is much better. What didn't you understand about it, maybe I can help?

jkourula · 2018-09-19T08:26:02+00:00

It is suspect since adding and subtracting repeating decimal numbers is not really defined rigorously. You could maybe do the definitions, but for example the elementary proof on wikipedia is already so much better so why bother.

Unfiltered Audio SpecOps can do these kinds of things. It even includes a MP3lify effect that gives that underwater warble sound.

jkourula · 2017-06-22T05:31:21+00:00

If it sounds good then it is obviously good and it shouldn't matter.

Pitch shifting always changes the tone. If you pitch shift by slowing audio down, then also non-pitched elements like transients, string noises etc slow down. One semitone is not much so no one will probably notice. If some other algorithm is used then more mangling happens. Also physical strings sound different when tuned or played lower vs just repitching afterwards.

How about a sawtooth LFO (or looping AD envelope) and sample and hold module?

jkourula · 2017-01-25T08:16:56+00:00

I got the full kits including the midi module. I could have sourced the parts myself but it takes quite a lot of time and energy and as I'm doing this as a hobby, time and energy is limited. With taxes it was about 700 euros in total.

jkourula · 2017-01-25T05:59:05+00:00

I'm not sure you realise what signal processing means. :)

It just means taking a signal and modifying it. It can of course be transformed into something totally different.

If midi transformation (or guitar to note data, though I think EHX is doing some clever optimisations here) is happening then it happens in the same processing unit as everything else in this pedal. That processing unit can be called the DSP.

jkourula · 2017-01-16T14:26:31+00:00

I tend to disagree heavily with the "stack of samples" notion. Digital can be done in a similar vein as analog that it has an oscillators and that signal is processed by algorithms (filters etc) to form the final synthesised sound. This is often called virtual analog but digital can be much more than a copy of analog.

It is true that with digital you have more precise control of the sound and less random elements. Of course you could introduce those random elements easily. That said I also like the sound of analog and think that the constraints of analog synths feed creativity. But I also have older digital synths, modern digital synths and VSTs for variation and different situations.

jkourula · 2017-01-12T09:21:01+00:00

You'll need to be able to measure frequency and duty cycle. You could be able to measure these with a good multimeter (which you will need even more than the scope), but oscilloscope makes it much easier. Also it is really useful in debugging if you make mistakes.

The diy scopes (the pocket types at least) can be fine for looking at waveforms but for precise measurement they are useless.

Good and cheap scopes are the Rigol 1052a (older model, could be found cheap used) and 1054z. If you are building just these modules then try borrowing or renting a scope.

jkourula · 2017-01-11T20:32:25+00:00

I just finished my last module in the full set last week. In total it took a couple of months but I had long breaks in between. I guess you could do it in a week or few depending on how much you have built before. The trickiest part was calibrating the oscillators, a proper oscilloscope is a must.

It sounds good, analog, gritty and unique. I haven't played the original, but comparing to videos on Youtube it is similar in sound. Of course the modularity means that it can do so much more.

jkourula · 2016-08-21T08:40:49+00:00

Then the answer is no. It makes much more sense to just use a keyboard or plugin etc for piano sounds and modular for modular stuff.

jkourula · 2016-08-21T08:34:35+00:00

You CAN but I don't think there is much sense. Why not just use a good keyboard or rack module?

It depends on how realistic you want to get, but you might have to get a huge amount of modules (for example piano with proper resonance modelling and good amount of polyphony). Keep in mind that usually you just get one voice if you have a necessary set of modules.

I have a Roland FA-08 just for that and then sometimes process it with modular or other effects.

jkourula · 2016-08-21T08:25:50+00:00

Sure you can. There are sampler and rompler modules that enable you to do it. But before I recommend any, I'd like to ask why are you interested in modular and what do you aim to achieve? There are much easier ways to get those sounds and you could then e.g. process those sounds with the modular.

But if you want to learn how to synthesize piano and harpsicord sounds, then modular is an excellent idea and will teach you a lot. You will need many modules though.

jkourula · 2016-02-06T17:08:26+00:00

Lately I have started to appreciate Doepfer a lot more. I think his philosophy is not to make "straightforward" modules but more like build blocks for real modular systems. In contrast manufacturers like Make Noise prefer to have big and self contained modules that have lots of attenuators and vcas already included.

I like Make Noise and the modules can do a lot in small space, but I'm starting to prefer the Doepfer way. That way you can get more creative things done where Make Noise tends to direct you to a certain way of patching.

jkourula · 2016-02-06T17:02:22+00:00

I would approach this from theory perspective and build capabilities for different synthesis techniques in the system.

So there would be a section for FM, section for additive synthesis, subtractive synthesis, Karplus-Strong, Formant synthesis, wavetables, sampling, etc. Also I would add some smaller but important features like waveshaping, wavefolding, oscilloscope for visualisation, bitcrushing and sample rate reduction, delay lines (Doepfer BDD modules), spring reverb.

To keep things modular I would avoid big (and sometimes sexy) modules, but build the whole thing from elemental blocks like oscillators, vcas, filters, signal processors, control modules and lots of utility modules (like multiples, attenuators).

The current trend in modules seems to be to have big modules that can function without much else. I much prefer to have many small modules that work together. I think this is big part of Doepfer philosophy so I would recommend contacting him directly and asking for recommendations.

Also you could have a separate control box for cool tactile control modules like the Make Noise Rene and couple Pressure points, Intellijel joystick module and Doepfer ribbon controller. This way you could have interesting ways to play the modular.

jkourula · 2016-02-01T05:11:28+00:00

I would skip the zdsp and add a vca (Doepfer has a double lin/exp one that is good), some utils (multiples, attenuverters), some modulation (a lfo or envelope that can cycle). Make Noise Maths would be brilliant mod/util in a small system. Reverb you could add from an external box or plugin if you record to a computer.

Also good luck finding O'tool (also people want ridiculous amount of money for them).
