So its just plugging in the Teensy and click a Button on a Webpage? Im all in for that one!

Audio to the Audio Shield goes vie I2S, not I2C, I2C is just used to control the Codec, so need to worry your Display interferes with Audio Data.

Easier than BASIC? Should i have a look at it? It just because i feel my Code looks like BASIC code in a C++ Wrapper ;-)

I dont use 3.5/6 or 4.1s :-) Honestly whats easier? Copy a file (where is my card ????) to a SD (where is my card reader????) and plug it into a board (dont forget to make the SD Slot easily acessible - my Teensys...

Right! NEED * MORE * COFFEE and tried to edit Post #3. I wasnt aware that this options runs out after some Time??? Most recent (branded) PSUs work just fine, only the cheapest ones (hence the ones with older...

Ferrite beads additionally would supress any HF noise, but have no impact in audible range.

Moin Ben! First, you have t understand that you NEVER should run Audio Circuits directly from a non trustworhty, possibly unstabilized and unfiltered rail, especially if you have a common GND with some digital...

Any chances the MicroMod 3.2 will be available commercially sometime?

Besides the fact that S/N ratio isnt not really an important parameter to a Synth (at least i didt care for it, "musicallity" or usabliity are magnitudes of more importance) - does it make sense to measure on a...

Maybe its easier to have the Sensors away from the Teensy+Display?

OK, good luck then.

Its easy: every time you connect something (quick enough.... see here "Why do some synths produce clicks") and there is a voltage difference it clicks. It doesnt matter if you connect it via plugging in or a relay -...

You still create a Click with these types of Relais, i guess you would need a "make before break" type of relay. Besides this, a relay for preventing a switch on pop is deep in overengineering terrain. But thats just me.

What exactly do you want to achieve with this??? Whats the difference between plugging in a jack and switching via a relais? And: whats the criteria for switching on the Relais?

Paul, thanks for the quick response! I just tried to save me the hassle of multiple 595s for driving all the LEDs in my next Project and one single PIN to drive approx 30 LEDs + they all can be RGB now looks pretty...

Teensys PCB Qualitiy is top notch and i never had an issue the last 50+ teensys i soldered. If you have problems soldering to it it may be these are more on your side and you might possibly need a little more practice?...

Sadly this doesnt integrate well with most projects.....

Time to think about your Gain Staging if you overdrive something.

People will hate you for that DC offset. At least many people i know. Time to think about your gain staging. Or your Monitors ;-)

Why do you have a physical bass boost? If you feel you are lacking low end you could either implement a Sub Oscillator (good idea anyways) or ad a bit digitally (via adding HP output from a SVF to the Sum at the end of...

You can also order them via AliExpress for about 6ct/pc They are as cheap as resistors (nearly) so the easiest Solution is to just buy a few hundred PT8211 and keep them on Stock. At least if you dont plan to sell...

... so basically it hasnt anything to do with the Shruthi anymore, right? May i propose to change the Threads title then?

How do you plan to generate the CVs for the analog Filter Boards?

- Teensy with DAC output: does it work ? Could analogWrite of a packet of Voltage values work? Yes.

Why dont you just use the Teensy Audio Systems AudioSynthKarplusStrong Object to directly synthezide Plucked Sounds? The onboard DAC is capable of at least 44,1 kHz @ 12 Bits.

...and why dont you just use 4 Encoders instead if the Pots?

Why do you use a ATmega for the Pots - it will be the bottleneck if you want to have fast Modulations. Have you tried any kind of A/D instead?

Man, this one is beautiful! Have a very nice xMas, all the best for you and your loved ones!

Picture please!

Thanks for your superquick response!! Will try this asap later - ill have to leave as well getting some things we missed yesterday for xMas.... ;-)

Next Problem: the new Library doesnt compile older Sketches properly anymore for the LC: #include "EncoderTool.h" using namespace EncoderTool; Encoder encoder; int value=0; void setup() {

Adding EncoderTool-master from today to my /Dokumente/Arduino/Libraries folder in addition to EncoderTool-2.2.1 now compiles the Code in question: #include "EncoderTool.h" using namespace EncoderTool; Encoder...

Nope, heres a snippet of the Code from a Sketch where it works: pinMode(stopLEDpin, OUTPUT); analogWriteResolution(12); encoder.begin(encoderA,encoderB); // A=0, B=1 encoder.setValue(0); ...

Puh - i thought i am to dumb to understand..... I can confirm, first calling a Serial.println("Irgendwas"); is a workaround. I got a bit crazy, because i just copied + pasted these lines from another Sketch and it...

Thanks for that hint - TSSOP looks somehow solderable by hand so one can avoid Breakout Boards. So i use them simply with the i2s Output Module form the Audio System? Just like the PT8211??

I guess the trick is an LFO means LOW frequency oscillator. Low as in "much lower than the modulated Signal". Your Pic above reminds me more of FM, as the modulating Oscillators frequency is roughly the same as the...

Nope, i get the effect of a classic VCA modulated by a LFO : change the Amplitude according to the LFOs Signal. As staded above, you should feed the AudioAmplifer Object with Values from 0-1.0 do miin the VCAs...

You could use a simple timer driven Phase Accumulator and a Huuuuge Lookup Table for your LFOs and have these modulate an AudioAmplifier Object. At least its what i do. And: Yes, im Interested what you did there.....

Just as you would do from your former only window. Dont feel ashamed - i had the same Problem......

Why not just put the code in different Tabs? Click on that tiny downpointing triangle up there on the right side....

What better Codecs someone could possibly solder manually (DIP or SOIC) are feasible?

You are using a simple Voltage divider for your -5V Offset Voltage, so every Noise on the negative Rail will bleed into your Circuit. How accurate are your A/D readings then?

OK, i worked it out. Somehow. At least a feasible, but probably maximum unelegant way to get the Waveforms converted: 1° Resample you singlecycle (16 Bit Mono) waveform so you get exactly 256 samples length, using...

For desoldering Components: maybe add a touch of leaded solder. Helps with THT any time.

I dont understand why a "clipped" Signal should damage speakers just by being "clipped", whatever clipped means.

What about a standard Limiter like this: https://www.thomann.de/de/drawmer_sp_2120.htm It even has a KeyLock ;-)

So inside the Cobalt8 is a Teensy??
