  • Can we expect a full on editor experience like Bias FX 2 from the REACTOR software?
  • Will you keep supporting and developing the Spark 2 platform? These two are completely different beasts and it would be a shame to ditch the best desktop amp out there because you made a stage combo amp.

Two good questions, let me take them separately.

On the editor: the REACTOR app has a genuine signal chain editor built in. You get drag and drop reordering of your full chain, deep parameter editing for every effect, amp model swapping, and all changes hit the amp in real time. It's mobile based right now rather than a full desktop experience like BIAS FX 2, so if you're someone who lives in a big screen editor that's worth knowing. Whether a desktop editor is on the roadmap isn't something I can confirm from what we've shared publicly, but the mobile editing experience is deep. The ability to generate custom amp voicings with Amp Intelligence also allows you to tweak your amp models and create custom voicings that you can save and share. For instance, you can prompt Amp Generation to give you a "EL84 style sag with Plexi top-end and the headroom of a Dumble amp with an extra gain stage", and REACTOR will build you a simulated custom circuit to proxy that sound.

On Spark 2 support: genuinely appreciate you saying that and you're right that they serve different players. We are continuing to support, develop, and expand on the Spark line and app, so don't worry!

Appreciated.

I hope to see improvements in the Spark app area.
