In addition to the HP/LP filters, there are also 3 ‘preamp style’ pass-through programs you can use to give anything some subtle analog flavor. Everything was sampled from 2 pieces of vintage hardware- a console eq section and an outboard eq unit. Unlike almost all Nebula filter/eq programs, these were sampled with dynamics.
The programs for the console, I’m calling “Baltec”, and they were made from a rare and very highly regarded UA8000 mixing desk. One HP, one LP, and 2 pass-throughs, all sampled in stereo. Different channels on the desk were used to make the different programs and this is why there are two different pass-through programs, although the differences are very subtle and probably not something you’d really be able to tell apart. Filters are 12dB/oct.
The programs from the EQ unit, I’m calling “YouRay 546”, and yes it is related to my previous “YouRei” set which was based off of a 565t model filter unit, whereas this set is based on the 546 EQ unit’s filter section. The 565t has 18dB/oct filters but here you get 12dB/oct. You get an HP, an LP, and a single pass-through from this piece, all sampled in mono (doesn’t mean your audio willbe converted to mono, just that both channels use the same impulses). Like the565t, this unit has nice output transformers so you can get some nice tone from the filter programs or pass-through.
Lastly, due to time constraints during sampling, these filters are not fully variable. Instead I sampled several fixed position steps for each filter, across their range.
Here are the sampled high pass frequency positions, in Hz:
Baltec HP- 40, 60, 110, 200, 300, 400, 550, 750, 1150, 1300
YouRay HP- 80, 100, 140, 200, 450, 1000
Sampled low pass freq positions, in kHz:
Baltec LP- .9, 1.5, 2.5, 3, 4, 5, 6, 8, 12, 16
YouRay LP- .4, .6, .8, 2, 2.4, 3.2, 4.5, 6, 10
As you can see there are plenty of frequency positions for your mix filtering needs!
