## Solderbox Description
Solderbox is a compact semimodular synthesizer, made in collaboration with Jakob Haq. It is heavily based on Jakob's own modular rack design (which features a lot of modules made by hand).

The app is designed to offer a set of modular functions that is both comprehensive and eclectic, including several tools for generative synthesis, random signals and the surgical mangling of audio waves and modulation signals.

A lot of effort went into making everything sound and behave as analog as digitally possible (with the exception of the unashamedly digital Entropy lo-fi effect processor). Additionally, the built-in Instability Engine injects the subtle fluctuations simulating the effects of crosstalk, leaky signals and expired electrical components. This is a living instrument with a soul of its own.


- Full Audio Unit compatibility (AUv3 instrument, audio effect)
- Universal design (iPhone, iPad, MacOS AUv3)
- Built-in Pulsequencer (LFO-based generative melody generator with custom scales)
- 4 mode Low-pass filter (6, 12, 18, 24 dB)
- 3 voice polyphony
- Drone mode
- Stackable patch cables
- DIY Lo-Fi digital delay circuit emulation
- All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice)

## Solderbox Reviews in United States

### ****- "Very Good, could be Great"
I know next to nothing about modular and I got this to learn.  Some knowledge is needed because just plugging things in at random often has no effect. I suspect this is because some modules need an input in order to provide an output.  One small change that could help people visualize the signal better is to have a status LED next to each output, similar to the LFO status LED. Or maybe make the wires glow brighter with their signal.  Another option is to offer an oscilloscope module but I suspect that would require more effort.

### ***** "Another rare gem like Hilda"
Bram Bos makes the best (indie) apps for iOS. This is no exception. With help from Jaqob Haq, this is going to easily be considered maybe the best synth of 2024. It is very unique, as expected from Bram Bos and the videos and reviews don’t do the instrument justice. Just like Hilda, you need to really use it to understand how great it is.

### ***** "Semi-Modular | Fully-Fantastic | A New Favorite"
Another incredibly intuitive, well designed, deeply considered, and just all around fun instrument to make some noise with. Brams previous collaborations with Hainbach were brilliant, this collaboration with Jakob is no less so, it’s a fantastic collaboration I hope everyone enjoys as much as I have. 

I’m grateful, Bram, that you find those creators inspiring enough to collab with, so that he can share your software wizardry with us other musicians to get inspired by. Thank you! 🎶🎹🪗
