Yes, sorry.  We wrote help for the algorithm, but it's not being pulled up correctly by the app.  The algorithm name changed and the help file still has the old name…

EQ Compressor – [EQCOMP]

EQ Compressor offers a multi featured parametric equalizer along with a pre/post compressor to give you the freedom in shaping and designing your instruments tone in mono and stereo . It features 2 completely parametric bands with a wide range of frequencies along with low shelf and high shelf filters for easy manipulation of your tone. In addition, it features a unique compressor which can be placed before or after the EQ .The compressor gives you the flexibility to additionally shape your guitar tone the way you desire. The EQ Compressor also features a 12 dB boost at the output to push the amp to awesomeness or to boost for your soul tearing solos.

Gain 1– [GAIN1]: The gain for the first parametric filter. You can have boost by 12dB and cut by 18 dB.

Frequency 1 – [FREQ1]: The center frequency of the first parametric band. The frequency ranges from 100Hz to 1500Hz.

Width 1 – [WIDTH1]: Controls the bandwidth of the 1st parametric filter. A value of 10 represents a larger bandwidth while a value of 1 represents a narrower bandwidth.

Gain 2 – [GAIN2]: The gain for the 2nd parametric filter. Provides 12dB of boost or 18dB of attenuation.

Frequency 2 – [FREQ2]: The center frequency of the first parametric band. The frequency ranges from 1000Hz to 5000Hz.

Width 2 – [WIDTH2]: Controls the bandwidth of the 2nd parametric filter. A value of 10 represents a larger bandwidth while a value of 1 represents a narrower bandwidth.

Bass – [BASS]: Controls the gain on the Low Frequency Shelving Filter which is centered around 400Hz with a slope of 8dB/Octave. You can boost the low by +12 dB or cut by 12dB.

Treble – [TREBLE]: The gain on the High Frequency Shelving Filter which is centered around 1800Hz with a slope of 8dB/Octave. You can boost the highs by +12 dB or cut by 12dB.

Compressor – [COMP]: The amount of compression applied to the signal. The values to the left half of the knob will affect the Pre – EQ compressor and will increase the amount of compression as you move it anti clockwise. The values to the right half of the knob will affect the Post -EQ compressor and will increase the amount of compressor as you move it clockwise. The compressor is specially designed to vary the various parameters of a typical compressor such as the ratio, attack, release and the post gain to keep the loudness constant.

Trim – [TRIM]: Controls the level at the output of the signal path. Provides 12dB of boost or 12dB of attenuation.. The algorithm is designed to clip if there is too much gain inside the EQ and the red overload LED on the H9 Pedal will light up in this case.
