Signal-driven event sequencer The seq~ object is an event sequencer that is driven by a signal input. seq~ can be used to create looping sequences of control data that are synchronized to a phasor~. Cycling '74 MSP MSP Functions phasor~ input, commands, messages to be sequenced TEXT_HERE TEXT_HERE sequence output TEXT_HERE dump output TEXT_HERE id on read, (bang) when done reading TEXT_HERE TEXT_HERE TEXT_HERE Causes information about the seq~ object's current sequence number, mode of operation (record, overdub, play) Causes information about the seq~ object's current sequence number, mode of operation (record, overdub, play) and total number of current events to be printed in the Max window. Same as anything. Same as anything. Same as anything. Same as anything. Same as anything. Same as anything. The seq~ object is used to record and play back messages. The seq~ object is used to record and play back messages. All events received in the inlet are stored according to the current value of the input signal. Any message can be sequenced except for commands to the seq~ object itself. The example shows a simple way to work around this limitation.
Note: seq~ can be used to sequence MIDI data if the MIDI input stream is converted into lists of MIDI events. This conversion is necessary to avoid outputting a corrupted MIDI stream which would occur if only the raw int messages of a MIDI stream were sequenced individually and the seq~ object were not doing a simple forward linear playback. The word add, followed by an int, a float and a message, inserts a Max event specified by the message at the time specified by the float for the sequence number specified by the int. (e.g., add 2 0.5 honk will insert the message honk to be played at the halfway point of sequence 2.) The word add, followed by an int, a float and a message, inserts a Max event specified by the message at the time specified by the float for the sequence number specified by the int. (e.g., add 2 0.5 honk will insert the message honk to be played at the halfway point of sequence 2.) The word clear, followed by the name of a sequence, erases the sequence. The word clear, followed by the name of a sequence, erases the sequence. The message clear all erases all current sequences. Synonym for clear. Synonym for clear. The word delete, followed by an symbol that specifies a sequence name, a float and a message, deletes a Max event or events specified by the message at the time specified by the float for the sequence name specified by the symbol. An additional end time may also be specified. Here are some examples:

delete mysequence 5.: delete all the events at time 5 in mysequence.
delete mysequence 6.5 8.: delete all the events between time 6.5 and 8 in mysequence.
delete mysequence -1. 99. explosion: delete only the event explosion wherever it occurs. The word delete, followed by an symbol that specifies a sequence name, a float and a message, deletes a Max event or events specified by the message at the time specified by the float for the sequence name specified by the symbol. An additional end time may also be specified. Here are some examples:

delete mysequence 5.: delete all the events at time 5 in mysequence.
delete mysequence 6.5 8.: delete all the events between time 6.5 and 8 in mysequence.
delete mysequence -1. 99. explosion: delete only the event explosion wherever it occurs. Causes the contents of the current stored event sequence to be sent out the middle outlet. Causes the contents of the current stored event sequence to be sent out the middle outlet. The word dump, followed by a number, outputs only the sequence designated by the number. The word play, followed by 1, causes seq~ to begin Max event playback of the current sequence (set by the seqnum message) The word play, followed by 1, causes seq~ to begin Max event playback of the current sequence (set by the seqnum message) at the point of the loop specified by the current value of the signal input. play 0 turns off playback. By default, playback is off. The word offset followed by a number will offset the numbering of sequences by the specified number. The word offset followed by a number will offset the numbering of sequences by the specified number. The word overdub, followed by 1, causes seq~ to begin Max event recording of the current sequence (set by the seqnum message) The word overdub, followed by 1, causes seq~ to begin Max event recording of the current sequence (set by the seqnum message) in "overdub" mode. Recording begins at the current point of the loop and wraps around at the point where the input signal reaches 1, continuing to record as the signal passes its original value. The message overdub 0 turns off overdub mode. Performs the same function as seqnum. Performs the same function as seqnum. The word seqnum, followed by a number or symbol, sets the current Max event sequence being recorded or played back. The word seqnum, followed by a number or symbol, sets the current Max event sequence being recorded or played back. Reads a text file containing Max event sequences created using the seq~ object's write message into the memory of the. Reads a text file containing Max event sequences created using the seq~ object's write message into the memory of the. seq~ object. If no symbol argument appears after the word read, a standard open file dialog is opened showing available text files. The word read, followed by a symbol, reads the file whose filename corresponds to the symbol into the seq~ object's memory without opening the dialog box. The word record, followed by 1, causes seq~ to begin recording events into the current sequence (set by the seqnum message) The word record, followed by 1, causes seq~ to begin recording events into the current sequence (set by the seqnum message) at the point of the loop specified by the current value of the signal input. record 0 turns off recording. Recording is off by default. An input signal whose output is between 0. An input signal whose output is between 0. and 1.0 (usually the output of a phasor~) is used to drive the event sequencer. Same as anything. Same as anything. Saves the contents of all current Max event sequences into a text file. Saves the contents of all current Max event sequences into a text file. A standard file dialog is opened for naming the file. The word write, followed by a symbol, saves the file, using the symbol as the filename, in the same folder as the patch containing the seq~ object. If the patch has not yet been saved, the seq~ file is saved in the same folder as the Max application. It is optimized for continuous ramp input, but any signal passing through any range of values will work. Sequence events can be recorded in real-time or inserted with the add message. seq~ can contain any number of sequences, but only one at a time is active for playback and recording. Out left outlet: When playback is enabled with the play 1 message, the seq~ object outputs all events recorded at the time specified by the input signal. Out right outlet: The dump message will cause the seq~ object to output the contents of a specified sequence to be output in the form of a list consisting of an int which specifies the sequence number, a float which specifies the signal value associated with that point in time, and the int, float, symbol or list to be output at that time.
