The Business Card Synthesizer is a tiny synth that can be connected to a Business Card Sequencer, other synth gear, or played by itself.
These fun little kits were introduced at Knobcon 2018 as a build workshop. Now you can get your very own.
Headphones can be connected directly to the output of the synth, and there are plenty of knobs to play with, so you can easily make noises anywhere. Great for learning about synthesizers!
Features:
- Pulse, square, triangle, and sawtooth waves
- Glide
- 2 LFOs with pulse, square, saw, triangle and ramp shapes
- Attack / Decay
- Low-pass filter
- Sample and Hold
- Manual gate trigger (can be locked on)
- Course and fine-tune controls
Controls:
- S&H Button: Enables Sample & Hold, which disables the external CV IN jack and uses LFO1 and LFO2 to determine oscillator pitch. LFO1 sets the sample rate (SHAPE is ignored for this), and LFO2 is the wave that gets sampled.
- GATE Button: Manually turns on the gate so sound comes out of the synth. This control is momentary, but you can latch it on by tapping the S&H button while holding the GATE button down.
- COARSE TUNE: Adjusts the pitch of the oscillator up or down in large increments
- FINE TUNE: Adjusts the pitch of the oscillator up or down in fine increments
- SHAPE: Changes the shape of the wave produced by the main oscillator (VCO). Turning this control fully CW gives you a triangle wave. Start turning it CCW takes you through sawtooth/ramp, then at about the 12:00 position you get a square wave.

Perfect, works just as described! A one-of-a-kind product. Division 6 is the best!

In conclusion, I purchased this product twice and both times it was defective, so I returned it. This product had the same problem with both orders received.When the gate was turned on and off, a "beep!" noise of the same pitch was always heard in both cases. No matter if I changed the attack or release settings, the oscillator, or the pitch, the noise was always heard. It made beeps before and after each pronunciation, making it useless as an instrument for playing pitches. It might be interesting as a machine that generates flashy noise using 2LFO and S&H. I return the product and reordered it, but it had the exact same symptoms, so I returned it again and gave up on purchasing this product.Then, I heard from a friend's friend who had experienced the exact same problem with this product. A few years ago, he complained to Division 6 about noise issues with the product, and they asked him to show a video of the noise. He took the requested video of the noise and showed it to Division 6, but after exchanging a single email, they stopped contacting him, and in the end, without receiving any exchange or return, he went to sleep crying.If I had heard about that beforehand, I wouldn't have ordered it. I can't trust Division 6 after years of not fixing the noise issues in their products.
