Description

Klankwelle is a modular synthesizer for iOS.

Create up to 8 synthesizers at once and control them with a built-in keyboard or a 16-part step sequencer. Or play them with an external MIDI source. Fine-tune your sounds with a dynamic compressor and a 10-band graphic equalizer.

Making a new synthesizer is easy: just add modules with a double-tap and wire up your architecture by dragging between connectors. Available modules include:

OSCILLATORS
Sine, Square, Sawtooth, Triangle, Noise, Ring

FILTERS
Lowpass, Highpass, Bandpass, Allpass, Notch, Peak, Formant

ENVELOPES
Linear, Quadratic

EFFECTS
Fuzz, Comb, Echo, Bitcrush, Auto Gain

LOW-FREQUENCY OSCILLATORS
Sine, Square, Sawtooth, Triangle, Linear Trigger

ARITHMETIC
Add, Subtract, Multiply, Convolution

FEEDBACK

CTRL

Supported MIDI messages: Note on/off (velocity sensitive), Pitch bend, control change, program change

Wonderful Synthesizer!

This is without a doubt an amazing synth and my favorite synthesizer app at the moment. There are only a few minor issues I would like to point out to the developer or any beginners. Dragging the modules is sometimes difficult and glitchy. Naming and sorting patches should have a better interface. The keyboard should be redesigned in my opinion, maybe having different modes of a piano layout, a chord layout, and the current layout. Zooming should be reworked in some manner that is less limiting. While this may seem like a long list, this app is one hundred percent worth your time. Great work to the developer!

Phenomenal App

You can do so much with this app, it’s hard to believe that it’s free. Whether you want to mess around and make robotic bug noises, get your feet wet with modular synthesis, or compose an electronic song, Klankwelle has got you covered. If you’re new to modular synthesis, there might be a bit of a learning curve, but it’s definitely worth it. Don’t be put off by the minimalistic GUI, this packs a punch.

I read that the developer has plans to add a sampler in the future, and I certainly hope he does. I would also like the ability to have multiple patches per connection (to route one output to multiple locations, to route multiple sources to a single effects unit, etc.) The ability to have slower attack envelopes (for slowly building pads) would also be useful, but now I’m just dreaming.

I debated giving this 5 stars because of how powerful it is for a free app. The only reason I went with 4 is because the interface can be a bit finicky at times (I’m trying to change a parameter—not move the entire module, etc.). I’ve also had the app stop outputting audio (though it continues to operate as if it is) a few times. This is usually remedied by closing and re-opening the app.

All in all, Klankwelle is great!

Great with one little beef

I use this app a lot and I enjoy it thoroughly. The sequencer is hard to operate though. It’s just not that intuitive. An extra visual would help a lot. Like a knob or if the color of the selected step changed with the octave. So you can do a corse tune visually and a fine tune looking at the actual note.

Other than that it’s pretty much all I need
