TAPLFO 3C – Squashing the bug

Posted by & filed under LFOs, Projects, Stompbox stuff.

We’ve recently discovered a bug in the recently-released TAPLFO 3 code (how embarrassing!). The problem only affects the tap tempo feature of the TAPLFO3. Other chips like the VCLFO or STOMPLFO aren’t affected. We’ve fixed the code, and while we were working on it, we also improved the switch debouncing routine to be more tolerant of bouncy switches. We’re offering anyone who has an affected chip (a TAPLFO 3) a free replacement with the TAPLFO 3C. Please get in touch and send us your… Read more »

TAPLFO 3C tap tempo LFO

Product

The TAPLFO chip adds a powerful feature to your LFOs: you can set the LFO frequency by tapping a tempo on a button connected to the chip, or by changing the Tempo CV. With this chip you can build tap tempo effects units or stompboxes, tap tempo controlled drum machines or tap tempo sequencer clocks. All of these are described in the datasheet below. The LFO can produce 8 waveforms, including a random (sample & hold) wave. All the waveforms… Read more »

Tap Tempo LFO (TAPLFO V2D)

Posted by & filed under Projects, Synth DIY.

2018 Note: Obsolete! This chip has been superseded by the TAPLFO 3 The new chip adds several features, has additional waveforms and improved resolution, and also no longer requires a crystal. It’s an improvement in pretty much every way! Head over and check out the data sheet. This simple Tap Tempo LFO is based on the PIC 16F684. You can set the LFO frequency by tapping a tempo on a button connected to the chip, or by changing the Tempo CV…. Read more »

Electric Druid chips: The Next Generation

Posted by & filed under Envelope Generators, LFOs, Projects, Stompbox stuff, Synth DIY.

In the last six months, we’ve been very busy here in the Druid workshop, developing and testing new versions of our PIC-based chips. This work is now complete, so I’d like to introduce the new chips. Why bother? What was wrong with the old ones? Ok, there wasn’t anything much wrong with the old ones, but things have moved on since 2008 when most of them were originally developed – ten years ago already! Most importantly, Microchip have released a… Read more »

STOMPLFO 8-pin tap tempo LFO

Product

The STOMPLFO tap tempo chip is a simplified 8-pin version of our popular TAPLFO chip. It is intended to replace the typical (and boring!) dual op-amp Schmitt trigger/integrator LFO that turns up in a million stompbox and guitar pedal designs. It provides 8 waveforms including two interesting random waves, and can generate frequencies from 0.05Hz to 25Hz. The LFO frequency, waveform selection, LFO depth, and output offset voltage are all voltage-controlled using 0-5V. Download Electric Druid STOMPLFO tap tempo LFO… Read more »
