Really enjoy this sequencer. It is beautifully constructed and gives my rack more of a hands on experience with playing. The clock divide and scales is a neat thing to add, and the touch plates work well... which can be tuned to allow less or more, touch control. Overall very happy with it.

Compact, works well, looks good, easy to make.

A wonderful experience all the way to my ears.

Works well, pretty straightforward build. I'm enjoying it!

Shameless plug here, Engine V2 is providing both the Bass and Lead: https://www.youtube.com/watch?v=xbVXKY6Es_A

Its just great

Great!

I ordered "Engine V2" in combination with "Exhaust V2" as an expander
to have access to all aspects of sound generation. The outputs of the
expander work well in combination with "Schlappi Engineering Boundary"
and enable interesting possibilities to create rhythmically coupled FM
sounds. That's what I was looking for on first sight.
Nevertheless, "Engine V2" is a successfully complex, well-thought-out
dual oscillator that can do everything from drone to melody and bass.
The genuine and friendly interaction with the customer should also be
mentioned, which shows that they are convinced of the product and stand
up for it.

Components were cheap and easy to source, soldering difficulty was appropriate for a beginner (like me), and the module does exactly what I needed...all at a great price! Love it, 10/10 would recommend.

Nice (and not too expensive) stereo MS20 with a very interesting resonance modulation matrix that deliver acidic "ping type" sweeps as we like. The bass part could have been more massive but are present anyhow. Cool !

4TRG is just the module for the job, everyone needs probability.

Very nice module - lots of experimentation options with the three filter types and the built-in vca.
Fun to build too!

The PCB/panel option is very easy to put together, with a low part count. Four VCAs in 4hp, how can you go wrong? The whole 4 Cubed series looks like great options for compact, affordable utilities.

Great design, easy build. Nice work!
