A non-band-limited triangle oscillator. Output ranges from -1 to +1.
| freq |
Frequency in Hertz. For efficiency reasons, only positive values result in correct behavior. |
| iphase |
Initial phase offset. For efficiency reasons this is a value ranging from 0 to 4. |
| mul |
Output will be multiplied by this value. |
| add |
This value will be added to the output. |
