Please note that the deveopment of Icarus2 was more than one year of work and we invested over €10.000 for paying professional sound-designers and artists. We do lots of free updates, but we can't do everything for free.
The price of €149 if already low for the feature-set that Icarus2 has. Originally we had planned €199.
€79 upgrade price for 400 new sounds + wavetables + samples + drum patterns + turning a synth into a workstation is also fair.
We also offer a grace period of 8 months where users get the upgrade for free.
We regularly will release big and free updates for Icarus2 with lots of new features. You will be able to download them for free here (as well as the many free updates for the other products):
https://www.tone2.com/download.htmlThere are no plans for paid updates in the future or new products.
Icarus2 most likely will be the final synth that we will do.
