The WT1 Wavetable Groovebox is a groovebox synthesizer designed to make sound and music quickly and easily. Taking inspiration from modular synth layouts; WT1's user interface is laid out like a sound easel with all controls on screen at once for immediate sonic tweaking and instant music-making.

WT1 s sports three synths with their own synthesis types: super saw, wavetable and vector. Each synthesizer includes a step sequencer for sequencing notes and amplitude, and includes independent effects; reverb, chorus and delay.

For the price of coffee, why not make some melodic sounds with WT1 Wavetable Groovebox!

3x synthesizer

Fun, needs some tweaks

It’s loading off center on 11 inch iPad Pro. Makes it so you push wrong buttons (just wiped out a patch while trying to hit save button but it thought I was pressing load).

Almost there, just need to see what’s going on with the UI

More than I'd expected

I've quite enjoyed this series of groovebox apps from Designbypaul - much more than I thought I would.

They're surprisingly fun, and useful beyond mere novelty.

This one has already made its way into a recent track, and I am sure it will make an appearance in future sessions.

The focus on a single DSP/synthesis paradigm is great for eliminating the bloat / menu diving of so many other groovebox apps.

If I were to make one criticism: when clipping occurs - it doesn't handle such things very... Gracefully. It's a harsh, digital clipping. The absence of proper level/output meters makes it difficult to discern the source of such clipping - to find the culprit. One must adjust each generator/level and listen until things are sufficiently tame. A minor issue overall.

Considering what you get for the price, it's a no-brainer.

Close, but not ready for prime time

Paul’s machines makes some great sounds and are a lot of fun to play with. It’s easy to lose yourself in the sound engines and in different sequencer pattern time and length values. The controls are intuitive and fun to tweak while the sequencers are running.

You have free reign over pattern length and speed of each sequencer, allowing for some wonderful polyrhythmic sounds!
