Rosen Digital has announced the release of Pulse, a cross-platform impulse response loading platform powered by Ignite Amps and featuring the “Pulse Cab” IR cabinet built into the plugin, which has a tasteful interface with a dual IR cabinet design with mono, dual-mono and stereo routing configurations, among global input level and bypass controls in the top pane.
Both IR cabinets each have a bypass switch, a simple output level knob and a phase on/off control that will invert the phase of a stereo channel independently. There are two buttons that provide the option between the pre-loaded “Pulse” impulse and “Ext. IR”. When selected, the latter of the two will open a browser window below the main controls with a navigation link to your folder of choice so you can load third-party impulse responses into the plugin.
There are also buttons for isolating cabinets “A” & “B” for monitoring purposes, a “Balance” knob (which only works in mono and dual-mono configurations) and a few basic controls down below for processing the two signal outputs differently, such as stereo panning, high-pass and low-pass filtering and up to twenty milliseconds of delay, which helps to create a nice wide stereo image.
I don’t ordinarily use guitar cabinet simulation software mainly because I find even the best IR cabinets sterile and harsh as a result of the sample-rate limitations in digital signal processing. However, I was surprised by how efficiently Pulse implements real-time sample rate conversion, which Rosen Digital describes as “the achilles-heel of all other IR loaders.”
For a limited time, Rosen Digital is offering twice as many impulses per-pack and will update their existing line of impulses in their new format as new cabinets become available. If you’re interested you can check out their extensive line of guitar cabinet impulse responses on their website here.
