Axe-Fx III Firmware Release Version 17.00 Public Beta


Release notes?
Version 17 introduces FullResTM Impulse Response processing. FullRes processes IRs up to 64K points with zero latency using a novel technique. This provides up to 1.37 seconds of response time. Seasoned producers and engineers often mix in “Room Mics” during recording to increase the depth and liveliness of recordings. However, the typical live room has a reverb time of 500-700 milliseconds, well beyond the 20-40 ms afforded by typical IR processing. FullRes allows capturing the full response of a typical live room and even the response of small-to-medium halls and clubs. FullRes can also be used for convolution reverb applications for reverb times less than 1.37 seconds.

NOTE: FullRes processing is currently only supported on the Axe-Fx III Mark II. The original Axe-Fx III has less non-volatile memory and therefore does not have the necessary resources to store the IRs.

The IR Player block and the Cabinet block both support FullRes IRs. The last two slots of the Cabinet block support FullRes. This is sufficient to provide two room mics, a left and a right, along with two direct mics within a single Cabinet block.

The two IR Player blocks have been combined into a single, stereo IR Player block with individual level and pan controls for each IR. Setting the IR Length to OFF defeats the IR. A Mix control is also provided so the block can be used as a convolution reverb. A Mode control allows the two IRs to be in parallel or series. When in series the individual level and pan controls are defeated and removed from the UI.

The new FullRes User IR bank supports up to 64 FullRes IRs. When capturing an IR selecting the USER FR bank will automatically set the IR Type to FullRes. Likewise, when setting the IR Type to FullRes the bank will automatically be set to USER FR. FullRes IRs can be processed with minimum-phase or auto- trim, if desired. However, minimum-phase is not recommended as this will tend to destroy the reflection information.

A FullRes Scratchpad is also implemented for auditioning IRs during the capture process. A new version of Cab-Lab is forthcoming which will support FullRes IR captures and management.

IR management has been completely rewritten providing smoother performance and better integration with Axe-Edit.

Increased Mic Distance range in Cabinet block to 3.4m (~11 feet). This allows delaying room mic IRs that have been trimmed to remove the leading silence. The alignment graph now features a Zoom control that changes the abscissa between 3ms and 12ms.

Improved Pitch Detection performance.

The UI has been improved to support double-tap of certain keys as follows:
• Double-tapping EDIT edits the previous block.
• Double-tapping HOME enters the layout grid.
• Double-tapping STORE prompts immediately.
• When on the Home page double-tapping the Quick Entry knobs does the following:
o A: Enters the Amp 1 menu.
o B: Enters the Drive 1 menu.
o C: Enters the Cab 1 menu.
o D: Enters the Delay 1 menu.
o E: Enters the Reverb 1 menu.

Various fixes and improvements.
