Afer pressing <ALT>+<c> you can toggle 13 options with keys <1><9> and <a><d>. The following list will explain every option:
The screen size can be changed by pressing <ALT>+<z>. In 132 columns mode some additional module information can be shown in the directory window. If the fileselector is busy scanning the current directory for files, you can interrupt the scanning with <ALT>+<s>.
You can delete a file with <ALT>+<k>. You will be prompted if you really want to delete this file. When pressing <y> the file will be deletet. If the file is stored inside an archive the file will be deleted from the archive. Note: If onyl one file was stored inside a .zip archive pkzip will leave an empty archive of 22 bytes on your harddisk. See section 5 on how to avoid this. The current file can be moved by <ALT>+<m>. You will have to type the new path in the path window into which the file will be moved. If the file is inside an archive it will be extracted. You can specify an existing .arj file and the file will be packed into the archive.4.2
The module information shown in the module information window can be saved to a portable ascii file. You may want this feature if you are a composer of music and want to trade your music together with already processed module information files. Start the fileselector and edit the information for the file. Then switch back to the directory window and press <ALT>+<w>. The fileselector will save a file with the extension .mdz and the filename of the selected file, which stores all module information seen in the module information window. If a directory is scanned and the fileselector finds such .mdz files they will be read and processed. The module information for all files in the current directory can be saved with <ALT>+<a>. You have to type the filename manually in the path window without extension!
You may want to change the entry type in the module information window if you have old amiga modules or a non-standard midi file. Very old Noise- and SoundTracker modules only had 15 instruments and no file identification. So the fileselector is not able to detect those files as valid modules and refuses to play them. You habe to insert M15 in the type entry. If the module does not differ between tempo and speed and is of the 15 instrument type insert M15t. Some ProTracker modules do not differ between tempo and speed too. It you habe one of those modules use MODt. A module player for PC called DMP introduced a feature called panning. To enable this (non-standard) feature insert MODd. If you want to play midi files with a second drum track on channel 16 use the MIDd option. Any other file should be autodetected correctly. If you habe renamed a module to a different extension (say hello.mod to hello.s3m) OPENCP will refuse to play it, because the file type is wrong. You could correct this by inserting the right file type in the module information as shown above. But it is recommended to rename the file to the right extension that tweaking the autodetetion of the player.
The current playlist can be saved into the .PLS format by pressing <ALT>+p. You have to type the filename without extension in the path window. A standard extension .pls is appended. The playlist can be loaded just like any other module from the fileselector or at startup.
The drive : is a special device which can be used to change the hardware configuration without leaving the player. If you access this drive you will see two subdirectories.
In the INPUTS subdirectory you can choose the device which will be used when sampling from external sources (when playing CD audio tracks or starting OPENCP in sample mode. The DEVICES directory displays all devices which where detected at startup. Normally you might want to change this if you want to save the next file as a .wav or .mp3 file to the harddisk.4.3 If you have a soundcard with hardware mixing support (Gravis, AWE, EWS) you can enable softwaremixing.
If you are the lucky owner of a soundcard capable of hardware sample playing4.4 you only have limited sample memory. If the sample data of the music is larger than the available ram OPENCP will try to reduce the sample size by applying the following steps:
Before downsampling the sample data OPENCP will search for the sample with the lowest frequency spectrum. This sample will be converted first. If enough space is freed up OPENCP will stop downsampling. If not the loader will continue until the sample data fits into the sound card memory.
The above behaviour can be avoided if a file is marked big by pressing <ALT>+<b> in the fileselector. The filesize will turn red. Now a file will not be loaded into the soundcard memory, but played with the internal mixing routines. This limits the size of files only to the size of physical memory.4.5
