Five tips and tricks for creating unique sounds with the Knifonium

Neil and Ed from Audiotent were kind enough to give us these 5 top tips for any of you looking to create your own sounds with the 26-tube driven Knifonium.

Tip 1. Gain staging 

Due to the tube-based nature of the Knifonium hardware, gain staging has a predominant role in sculpting the harmonics. Osc Mixer & Output master volume along with the amp mode can drastically alter the core sound. 

Tip 2. Ring Mod

The Ring Mod has a number of useful input and carrier options. One of our favorites for more experimental sound design is to use the feedback path as the carrier. This can lead to very unique textures and is a standout feature of the Knifonium.

Tip 3. Amplitude Modulation

AM can quickly be applied by clicking the ‘LFO to VCA’ switch in the VCA MODE section. Try setting the LFO speed to FAST and moving the speed amount to get your desired result.

Tip 4. Spread

The Knifonium has an effective way of creating stereo width within your patches. However, proceed with caution and always check the phase correlation. One way to keep the mono compatibility is to have OSC 1 with 0% spread and OSC 2 somewhere between 10-50% spread.

Tip 5. Filter Feedback 

Some really gritty tube distortion can be found when selecting the VCF as the destination for the feedback path. This can produce some magic when looking to create bass patches that have an edge to them. Select either Triode or Pentode output Amp mode and drive the master vol. Pull down the VCF Filter Frequency to tame the high frequencies. Next select the VCF f as the feedback destination and increase the feedback amount. Be careful of your overall output as things will get loud very fast! You can dial it back with the final Output at the top right of the plugin.
