We know Grainer, and the 1.1.0 OS that fixed the sync issues, are still fresh on the block, but we had some pretty neat dishes in the oven that didn’t quite make that release. So here is OS 1.2.0, a chance to put a few more little festive additions under the Tonverk tree. We’ve got new effects, even more options with the existing effects, a random mode for the arpeggiator, and some other little additions alongside further fixes and improvements.
New effect: Steel Box Reverb
A third reverb comes to Tonverk, and it’s a whole other flavor. Steel Box Reverb draws on early digital and ’90s plate reverbs, with deliberately wide parameter ranges that let you push sounds from tight metallic rooms to sprawling, resonant spaces. It can clang, bloom, or decay endlessly, making it equally suited to metal can tails or big, characterful ambience.
New effect: Filter Folder
Filter Folder combines wavefolding with filtering and distortion to reshape sound at a more fundamental level. By folding the waveform before it passes through a multimode filter and drive stage, it adds harmonics, grit, and movement that go far beyond traditional filtering. From subtle edge and density to aggressive, overtone-rich transformations, Filter Folder excels at turning simple signals into something far more complex.
More FX availability
If those two additions weren’t enough (for now) we’ve also extended Tonverk’s FX powers in other ways too. Daisy Delay can now be used on all tracks - and Frequency Warper can now be wielded on all audio tracks, bus tracks and mix. Use these two awesome options wherever your echoing, warped heart desires.
Random Arp
Random Arp introduces controlled unpredictability to arpeggiated patterns, reshuffling note order on the fly to generate evolving melodies and unexpected variations.
And more
There’s a few other stocking fillers too. Pattern mute, improved gain reduction and new sidechain sources for the compressor, shorter samples available to use on Grainer, and improved tempo stability when simultaneously receiving clock and large amounts of MIDI data from an external source, such as Octatrack. Plus various other fixes and improvements.
Check the full release notes to see all 1.2.0’s additions. And don’t forget to explore some of 1.1.0’s new features and fixes, from Tonverk’s new granular machine, to the Shape machine, to improved and reliable Auto Sampling & MIDI sync over DIN & USB. More to come in 2026!
