Synthesis

Band-limited oscillators

[hv.osc saw] - Band-limited PolyBlep sawtooth signal generator. more info

[hv.osc sine] - Same as Pd [osc~] added for convenience.

[hv.osc square] - Band-limited PolyBlep square signal generator.

Noise

[hv.pinknoise] - Cheapish pinknoise generator. more info

Envelopes

[hv.vline] - Envelope generator, replacement for Pd's [vline~] object.

Processing

Dynamics

[hv.compressor] - Compressor unit with Threshold and Ratio parameters. (Attack/Release is fixed at 40ms)

[hv.compressor2] - Stereo version of [hv.compressor].

[hv.envfollow] - Cheap envelope follower.

Effects

[hv.comb] - Comb filter effect unit.

[hv.flanger] - Flange effect unit.

[hv.flanger2] - Stereo version of [hv.flanger].

[hv.freqshift] - Frequency shifter effect unit.

[hv.reverb] - Simple reverb unit.

Filtering

[hv.filter allpass] - Allpass filter with Q control (Biquad).

[hv.filter lowpass] - Lowpass filter with Q control (Biquad).

[hv.filter highpass] - Highpass filter with Q control (Biquad).

[hv.filter bandpass1] - Bandpass filter with Q control, peak gain = Q (Biquad).

[hv.filter bandpass2] - Bandpass filter with Q control, constant 0dB peak gain (Biquad).

[hv.filter notch] - Notch filter with Q control (Biquad)

[hv.filter.gain peak] - Peaking filter with Frequency, Q and Gain parameters (Biquad).

[hv.filter.gain lowshelf] - Low shelving filter with Frequency, Q and Gain parameters (Biquad).

[hv.filter.gain highshelf] - High shelving filter with Frequency, Q and Gain parameters (Biquad).

Math Operations

[hv.exp] - Signal-rate exponential ( exp ), alternative implementation.

[hv.eq] - Signal-rate equal ( == ).

[hv.neq] - Signal-rate not equal ( != ).

[hv.gt] - Signal-rate greater than ( > ).

[hv.gte] - Signal-rate greater than or equal to ( >= ).

[hv.log] - Signal-rate natural logarithm ( ln ).

[hv.lt] - Signal-rate less than ( < ).

[hv.lte] - Signal-rate less than or equal to ( <= ).

[hv.multiplex] - Mix between two input signals based on a comparator.

[hv.pow] - Signal-rate exponent ( x ^ y ), alternative implementation.

[hv.tanh] - Static non-linear waveshaper.

Logic

[hv.dispatch] - Utility for organising parameter interfaces to other abstractions.

[hv.drunk] - Randomised walk number generator.

heavylib's Issues

hv.vline works in patch but won't upload

I added the hv.vline object to my pd patch on Windows 7. I pasted the file to C/Program Files (x86)/Pd/extra It works fine in the patch, but won't upload and gives the following errors:

_main.pd in "_main.pd" @ (x:0, y:0): Don't know how to parse object "hv.vline". Is it an object supported by Heavy? Is it an abstraction? Have the search paths been correctly configured?

_main.pd in "_main.pd" @ (x:0, y:0): There was an error while connecting two objects. Have all objects been correctly instantiated? Have all inlets and outlets been declared?

[comment text] in "_main.pd" @ (x:0, y:0): Connection made to non-existent inlet at [comment {u'text': 'null object placeholder (hv.vline)'}]:0.

Any ideas how I can resolve this?

hv_vline~

1. Doesn't work with [0, 1 $1(, requires [0 0, 1 $1( instead.

2. Output envelope is different from [vline~] and can substantially change the sound when very fast envelopes are required for things like granulary synthesis.

[hv.filter peak] misses the gain inlet

While most [hv.filter] variants have two parameters, the peak variant has three, namely the additional gain level. Since it would be desirable to set the gain by message, a third inlet is needed.
This would also imply that all the filter abstractions in the filter/ folder get a third inlet (if needed or not) to get rid of a "inlet->xxx connection failed" error message.
I would be willing to submit a pull request for this issue.

list count

Hello. I know the [list] object is not supported, so is there a simple way to reproduce the functionality of [list length]? e.g. [4 6 2 8 7(>[list length]>[5)

hv.objects not found ¿?

" c:\Python27\python.exe hvcc.py main.pd -n noiseRevX -g unity -o ./noiseRev11/

1. Error pd2hv: main.pd in "main.pd" @ (x:0, y:0): Don't know how to parse object "hv.reverb". Is it an object supported by Heavy? Is it an abstraction? Have the search paths been correctly configured?
2. Error pd2hv: main.pd in "main.pd" @ (x:0, y:0): Don't know how to parse object "vline~". Is it an object supported by Heavy? Is it an abstraction? Have the search paths been correctly configured?"

Tried to add to the path the heavylib-master but still doest compile .

Bela Code w/ Bela IDE

I was able to generate -g bela code with HVCC no problem. I tried running the C++ source through the Bela IDE and it yields the following errors:

Any ideas?
