Modifying sine, square and triangle waves?

Hey guys,
I’m currently working on a synth component to my drum machine for Android. I have basic Sine, Square, and Triangle waves set. I need help putting in variables that will modify the sound using sliders. Can anyone help with this?etu1yk

Here’s the code:

    void OnAudioFilterRead(float[] data, int channels) {
        increment = (frequency * 2.0 * Mathf.PI / sampling_frequency);
       
        if (sine == true) {
            for (int i = 0; i < data.Length; i += channels) {
                phase += increment;
               
                //sine
                data[i] = (float)(gain * (Mathf.Sin((float)phase * gain2)));

                if (channels == 2) {
                    data[i + 1] = data[i];
                }

                if (phase > (Mathf.PI * 2)) {
                    phase = 0.0;
                }
            }
        }

        if (square == true) {
            for (int i = 0; i < data.Length; i += channels) {
                phase += increment;

                //sqaure
                if (gain * Mathf.Sin((float)phase) >= 0 * gain) {
                    data[i] = (float)gain * 0.6f;
                }
                else {
                    data[i] = (-(float)gain) * 0.6f;
                }

                if (channels == 2) {
                    data[i + 1] = data[i];
                }

                if (phase > (Mathf.PI * 2)) {
                    phase = 0.0;
                }
            }           
        }   

        if (triangle == true) {
            for (int i = 0; i < data.Length; i += channels) {
                phase += increment;

                //triangle
                data[i] = (float)(gain * (phase < gain2 ? Mathf.Lerp(-1, 1, Mathf.InverseLerp(0, gain2, (float)phase)) :
                            Mathf.Lerp(1, -1, Mathf.InverseLerp(gain2, 1, (float)phase))));

                if (channels == 2) {
                    data[i + 1] = data[i];
                }

                if (phase > (Mathf.PI * 2)) {
                    phase = 0.0;
                }
            }           
        }         
    }
