Trigger a Single Ramp With an Audio Signal The ramp~ object generates a single signal ramp between a start and end value when it detects a change in an audio signal connected to its left inlet. The duration of the ramp can be a fixed value or based on the signal in ramp~'s second inlet. Cycling '74 MSP Trigger Input An output ramp is triggered when the incoming signal goes from a zero to non-zero value. Duration Input If a signal is connected to the second inlet, the ramp duration is set according to the current setting of the mode attribute. If mode is 0, the value of the duration signal at the moment it starts becomes the unchanging duration of the ramp. If mode is 1, the duration can be updated over the course of the ramp if the value of the signal changes. Start TEXT_HERE End TEXT_HERE Ramp Output A signal ramp from the start to end values. After the ramp completes, the value is 0 if the reset attribute is enabled, otherwise it remains at the end value. bang When Ramp Completes TEXT_HERE Duration If a float argument to ramp is present, it sets the initial value of the duration attribute. If a signal is connected to the second inlet, the duration attribute value is ignored in favor of the value of the signal. Converted to float TEXT_HERE Set duration or ramp start and end values In left or second inlet: sets the ramp duration (only used if no signal is connected to the second inlet)
In third inlet: Sets the ramp start value
In right inlet: Sets the ramp end value Trigger ramp, set duration, or set ramp start and end values A signal connected to the left inlet triggers the ramp when it goes from zero to non-zero
A signal connected to the second inlet sets the ramp duration
A signal connected the third inlet sets the ramp start value
A signal connected the right inlet sets the ramp end value Curvature The curve attribute sets the parameters of the exponential function that generates the non-linear output. It can range between -1 and 1. For ascending ramps, values of curve less than 1 produce values above the linear input and values of curve greater than 1 produce values below the linear input. As curve values near -1 or 1, the curavture becomes more extreme. Duration Sets the duration of the ramp in milliseconds. The ramp object uses this value only when a signal is not connected to the second inlet. End Value Set the final value of the ramp. Sample Interval The curved output is a piecewise linear approximation of the exponential function. The interval attribute sets the number of samples used for each line segement. Values of interval must be a power of 2 between 2 and 64 samples. Larger values will produce a less accurate approximation but could be more efficient. If the signal vector size is less than interval, the actual segment length will be the signal vector size. 2 sample segment length TEXT_HERE 4 sample segment length TEXT_HERE 8 sample segment length TEXT_HERE 16 sample segment length TEXT_HERE 32 sample segment length TEXT_HERE 64 sample segment length TEXT_HERE Duration Mode Sets whether the duration of the ramp is recomputed if the value of the signal connected to the second (duration) inlet changes. Duration is set at the start of the ramp and remains constant TEXT_HERE Duration can change if the signal value connected to the right inlet changes. The total duration of the ramp is recomputed to take into account the elapsed time. For example, if the original ramp was 1000 ms, and the duration signal changes to 1500 ms after the ramp has been going for 400 ms, the ramp will continue for another 1100 ms. In this case the slope of the ramp will be reduced so it takes the extra time to reach the end value. Reset After Ramp Sets whether the value of the ramp resets to zero after it completes (reset equal to 1) or remains at the end value (reset equal to 0). Allow Retrigger During Ramp When retrigger is set to 0 (off), it is not possible to retrigger a ramp while a current ramp is in progress. When set to 1 (on), you may retrigger a ramp during the current ramp. The default value is 0 (off). Start Value Set the initial value of the ramp.
