Although named as such, the TSM 2040z Sub LowPass Filter is not a typical Low Pass Filter. Such filters stem from the era of the earliest polyphonic synthesizers. They were designed in parallell to the filters of the monophonic synthesizers, and in the first stages of development produced bass enhancements at high resonance frequencies. However, they lacked gain compensation.
Returning to the beginings of filters, inspired us to create a Sub LP filter.
In TSM 2040z we retained the charm of the low frequency boosting characteristic of some early polysynth filters.
Bass Boost is adjustable up to the +12dB for the selected low frequency. The boosting of sub-frequency can be adjusted within the range 40-160Hz

Signals coming through the TSM2040z Lowpass filter are boosted with sub frequency enhancement.
The Lowpass section of the filter include various modes: Brickwall (which doesn't have a slope) and Lowpass Variable dB/oct slope modes (12-48).
The Resonance curve changes the attenuation character of the resonance.
The Crasher can be used to add saturation or distortion as desired to the filtered sound as a filter-destruction effect.
The Limiter can be used to limit overclipping of the filtered signal keeping it warm, fat and soft.
Sub bass on the Resonance is the thing which makes it loveable.
Test the sub frequency boosting power of the TSM 2040z SLP filter for yourself.

Hi there.
This filter work in the same way, how previously working filters of some early polyphonic hardware synthesizers.. Like a early versions of Octave Cat, Sequential Prophet-5 rev2 or RSF Kobol, and other synthesizers, also very know for SSM 2040 filter chip. Today, however, musicians look on the SSM 2040 as being the"best filter chip ever".
Early filters of poly synths producing low frequency (sub) boosting at the resonance increase. Later, newer filter chips fixing this problem - synthesizer manufactures turned predominantly to using CEM filters by Curtis. These chips were more stable filters, but had a completely different character to the SSM. Newer SSM chips after CEM popularity lost the charm of the 2040.
TSM 2040z - is not about concrete emulation, it more about filter ideology from early poly synths, that have own character of filtering.

Test it right now, how beautiful Low Boost resonance can be, with some modern additions.

UPADTE v.1.0.1 - already in the shop:
- Fixing bug of FM modulation knob (in few filter modes (LP18, 30, 36, 48) no reaction to FM changes)
- Fixing bug of Crasher modulations

I really wish you had extended the intro price a bit on this and xLPG. It took me more than a week to get my head around them. It would be nice in general if intro prices for new products lasted the 30 days of the trial to really figure out if they will work.

New in 1.1.0:

Bugfix: Filter no longer clicks with short pauses in the audio.
Bugfix: Device sometimes not sleeping to save CPU when silent.
Bugfix of the Resonance work in various filter type-modes

Now 3 FILTER MODES. Press to BOOST pop-up button and select between 3 filter modes:
1) Sub LP Filter: Resonance Boost selected low frequency.
2) Classic LP Filter: Resonance adjusts the resonant peak to the selected Frequency value. Boost of Low Freq is OFF.
3) Hybrid LP Filter: Resonance adjusts the resonant peak to the selected Frequency value and Boost low frequency at the same time.

Thanks for continuing to update your devices. Great product support!
Players are to MIDI what synthesizers are to waveforms.
