Superbooth 24: Erica Synths Bullfrog XL is Richie Hawtin’s educational-focused semi-modular Synthesizer in oversize.

Erica Synths surprised us by introducing the Bullfrog at the Sonar Festival 2023 last year. This semi-modular synth has two special features. On the one hand, it was developed in collaboration with producer and musician Richie Hawtin. On the other, the synth has a strong educational focus.

The synth is designed for children who would like to learn synthesis. But it’s also a full semi-modular synth with a VCO with FM, filter, delay, and more. At workshops or presentation, they explained the synth with an impressive oversized version. Now, this is also available. For Superbooth 24, Erica Synths releases the Bullfrog XL.

According to Erica Synths, Bullfrog XL is designed specifically for teachers to use in front of the classroom. Technically, it’s the same synth but has some differences.

Firstly, the size or let’s say, oversize. With its 820x505x65 (250 with the side panels) (mm) and weight of 8.3kg, it’s a very big synth.

Another difference is that Erica Synths added a built-in two-channel oscilloscope in the big version of the Bullfrog Synthesizer. There is also a second speaker. 

The rest is the same. It features an identical semi-modular 1 VCO + 1 VCF engine that can be expanded via the Bullfrog voice cards, including a sampler/looper, acid bassline, sequencer, and more.
