SoftPop, from BASTL instruments, is a desktop synthesizer with a mini modular patch bay. It contains six sliders for control, and a built-in speaker for playing on the go. The miniature patchbay uses small jump cables that are included with the SoftPop synth. It includes two triangle-core VCOs, with a state variable filter and modulation, all with a completely analog signal path. An external audio input allows one to use the SoftPop as a filter for processing, allowing it to be used in the vein of a guitar pedal. There are also three 3.5mm jacks that can be connected to the mini patch bay, making it possible to patch in or out modulation or audio from other Eurorack modular synthesizers.
Fully analog core and signal path
6 faders for controlling two VCOs and VCF and their cross modulations
Two wide range triangle-core VCOs 0 & 1
Quantizer for VCO 0 (auto-tuner)
VCO 1 has variable waveshape via the modulation setting
∞ resonant state variable VCF (bandpass, lowpass, highpass)
External input with gain and envelope follower for intuitive sync of VCO 1
Track & hold circuit for stepped modulations
Looping pattern generator with two patterns P1 and P2
Wooden handle backplate as accessory (sold separately)

Bastl SoftPop Synth With Mini Patchbay
The SoftPop from Bastl Instruments and Casper Electronics has two VCOs and a state variable filter that can self oscillate as well as a an interesting looping pattern generator and track and hold circuit for modulation. There is a mini patch bay with 25 points and 3.5mm jacks for patching CV and signals in and out of it with eurorack or other CV synths. This video shows the SoftPop by itself and with a small eurorack modular case with sequencers and some drum modules.
