Madrona Labs has released Aalto 1.5 – an updated version of its software modular synthesizer for Mac & Windows.

Version 1.5 has some major compatibility improvements for both Windows and Mac users. Performance should be dramatically improved on some Windows systems.

The new version has a new OpenGL-assisted renderer, so graphics are amazingly sharp, at full Retina resolution, in compatible hosts. This change means that using a tiny little Aalto window is now possible, which can really improve workflow on a laptop screen. (Note: Ableton Live does not yet support full-resolution rendering.)

Here’s the list of major changes in Aalto 1.5:

Fixed an issue that was slowing down Aalto dramatically on some Windows systems.

Fixed an issue requiring a runtime support pack on some Windows systems.

Improved latency through the patcher when running at large host buffer sizes.

Aalto now draws at full resolution on Macintosh Retina Display, in compatible hosts.

Aalto is now compatible with Soundplane version 1.0 and higher.

Fix mousewheel direction on Mac OS 10.7 and higher.

Accelerated drawing to the screen on Mac OS with OpenGL.

Optimized drawing scheduling to avoid glitches, especially in Logic.

User and factory presets now share the same location.

Improved ergonomics of patcher with larger handles and smoother graphics.

Fixed a drawing problem with bipolar dials.

Improved drag ergonomics for dials.

Free demo versions are available at the Madrona Labs site.
