Nothing comes closer to M7 hardware than Seventh Heaven Professional
— LiquidSonics official site
What is Seventh Heaven Professional?
Seventh Heaven Professional is a convolution reverb from LiquidSonics based on the Bricasti M7, using its Fusion-IR technology.
It includes over 236 Fusion-IR presets: 148 from M7 v1, 70 from M7 v2 and 18 miscellaneous. Samples are recorded at 96 kHz and resampled as needed.
Decay runs from 200 ms to 30 seconds and pre-delay from 0 to 500 ms, both syncable to host tempo. 32 early and late reflection patterns can be selected.
Channel formats range from mono and stereo to surround up to 9.1.6, so it fits both music and post-production work.
Fusion-IR technology
A convolution approach that lets decay and character be adjusted flexibly, which may suit those who want to tweak a preset's length.
236+ presets
148 M7 v1, 70 M7 v2 and 18 others, with expansion packs, giving a wide set of starting points.
Tempo-syncable pre-delay and delay
Pre-delay of 0-500 ms and delay of 100 ms-1 s can sync to the host tempo, handy for rhythmic reverb.
Multi-band decay and ducker
Includes multi-band decay multipliers and a ducker with optional external trigger, which may help keep reverb out of a vocal's way.
5-band master EQ
An oversampled 5-band EQ shapes the output tone, with a low-CPU mode and metering.
Surround support
Supports mono, stereo, 5.0 to 5.1.4, 7.0 to 7.1.6 and 9.0.4 to 9.1.6.
