What are the Model 12/16/12 The Model 12/16/24 is a FOH mixer with multitrack recording/mixdown capability and D.A.W. interaction. The Models have on-board "MTR" (MultiTrack Recorder) with straight forward "overdubbing"; "punch in"; and "auto-punch" capability. If you do not have or foresee a future need to edit tracks, do post-production work or master your work, then these Models should get the job done for you easily as a stand-a-lone production tool. If you do have or ever foresee a future need to edit tracks, do post-production work or master your work, then these Models will require using a D.A.W. program to accomplish those production tasks. How Are the Model 12/16/24 Configured If you have a Model 12 you have: A digital 10 track multi-track recorder/reproducer (1~10) A digital 2-Track mastering recorder/reproducer (11/12) The Model 12 operates 100% in the digital domain. It has "Live" mixer capability; Multi-track Recorder capability; 2-Track Master Recorder capability; and can also perform as a digital control surface for a D.A.W. program for interface, recording and playback via a D.A.W. The Models 16 and 24 operate in the analog domain. With the Models 16 and 24, you also have: A digital 14 or 22 Track multi-track recorder/reproducer (1~14 and 1~22 respectively) A digital 2-Track mastering recorder/reproducer (15/16 and 23/24 respectively) The Models 16 and 24 have "Live" mixer capability; Multi-track Recorder capability; 2-Track Master Recorder capability. When connected via USB to a computer/D.A.W., the Model 16/24 when set to "PC" can record to/playback from a D.A.W. rather than the internal MTR. However, the Model 16/24 cannot act as a control surface for the D.A.W. What Do the Model 12/16/24 Have Most in Common? All use WAV file format for their tracks. All have a Display Menu option that permits the proprietary 2-Track stereo master WAV files (Tracks 11/12; 15/16; 23/24 respectively) to be exported as a standard integrated stereo WAV file. All require using a D.A.W. for editing and mastering. They have no on-board editing/mastering capability. All can use a D.A.W. as an external multi-track recorder/reproducer, with the added benefit of the D.A.W.'s full editing and sound manipulation capabilities in addition to the sound manipulation capabilities available on the Model 12/16/24. Individual Inputs are hard-wired to the related specific Tracks (Input 1/Track 1, etc.) On playback, you hear the current stereo mix tracks (11/12, 15/16, 23/24 respectively); and can hear playback of previously recorded stereo mix tracks using the Bluetooth Channel strip. There's also an "SD Play" mode feature to play back Stereo WAV files in the Music folder. Compared to the DP-24/32/SD Portastudios The Portastudios are stand-alone, self-contained full 24 or 32 track studio tracking/mixdown/mastering production consoles, all within the digital domain. The Portastudio is a multi-track recorder/reproducer (24 or 32 track respectively). The Portastudio is a 2-Track mastering recorder/reproducer. The Portastudio is a 2-Track Mastering console. The Portastudio does not require any D.A.W. production capability, but tracks can be imported/exported to/from D.A.W. programs. The stand-alone tracking, production and post-production capabilities of the Portastudios exceed those of a stand-alone Model 24, and for some may be worth the less convenient need to work with the primary one level menus that permit : Assignment of individual Inputs to specific Tracks; Individual Input Effects (Compression,Exciter, De-Esser, Noise Surpressor); Individual Input and Individual Track Mixer settings (3 bands of parametric EQ, Pan, Phase, 2 Sends); FX selection and parameters; and Song Creation, Selection, and Maintenance. Phantom power selectively for Inputs 1-4 and 5-8. Suggestions: Get the searchable .pdf OM from TASCAM support site. This Sweetwater video demonstrates (IMO) the most efficient and effective way to make use of the Model 16/24 in a studio setting. Videos in the Forum "Videos" Sticky demonstrate how the Model 12 acts as a control surface for various D.A.W. programs. As I recall, the Model 12 can only control 8 tracks at a time in the D.A.W. Assure you're running the most recent OS release for your computer; and the most current version of the TASCAM firmware and software driver for your Model. Use only a TASCAM tested/approved SD card to avoid unexpected file and boot-up errors. The TASCAM support page has a list of tested/approved SD cards. Use a checklist to help assure that for each track during production, all the things that need to be turned on, switched on, or engaged are active (or in some cases disengaged/inactive). ================================================================= From the Model 24 Nov 2019 OM. Italics/Blue are the words found in the OM current as of November 2019 v#042862302. Text in black is my comments, as best I can decipher the OM. If you stitch together the scattered sections of the OM, you get : OM page 37: Recording; and the Block Diagram on Page 160 REC buttons (1-12, 13/14-19/20, 21/22) select the channels to record to the SD card i.e., when a Channel is set to "Live",PC,or MTR MODE and the Channel REC button is activated, and when the Transport REC button is pressed, a stereo mix of up to 22 channels will be recorded on the MAIN MIX L/R bus MTR Tracks 23/24 (the 2-Track recorder/reproducer). When the MTR is selected, the Channel input source also will be recorded to the associated MTR track. The Block Diagram suggests it's necessary to engage the Channel MAIN switch to get the stereo signal to the MAIN MIX L/R bus and thence to Tracks 23/24 on the SD card. When a MODE switch is set to “MTR” [Channels 1~22], the signal from the input jack on that channel will be recorded [to the associated MTR Tracks (1~22) if the channel REC button is activated and the Transport REC button is activated. A stereo mix of up to 22 channels will be recorded simultaneously on the MAIN MIX L/R bus MTR Tracks 23/24 whenever the transport REC button is engaged. The Block Diagram suggests it's necessary to engage the Channel MAIN switch to get the signal to the MAIN MIX L/R bus and thence to the SD card.] The MAIN MIX L/R bus does not have a REC button...it is always in recording standby. The signals of the MAIN MIX L/R bus ["Live", PC, or MTR] will always be recorded [on MAIN MIX L/R bus MTR Tracks 23/24] when the Transport REC button is pressed. [Block Diagram suggests it's necessary to engage the Channel MAIN switch to get the signal to the MAIN MIX L/R bus and thence to the SD card]. OM page 32: Managing Songs Song WAV files are saved for 22 [MTR] tracks and a stereo master file [MAIN MIX L/R bus MTR Tracks 23/24 ]...Songs [and related WAV files] are created/saved in the MTR folder on the SD card. OM page 24: SD MAIN MIX RETURN switch When this switch is on (pushed in)...playback of the stereo master file recorded on the SD card [i.e., the current stereo mix recorded onto MAIN MIX L/R bus MTR Tracks 23/24 in the MTR folder] is output from the MAIN OUTPUT and AUX OUTPUT MON 1/2 jacks. The sound of the MAIN MIX L/R bus [Channels 1~22] is not output. OM page 44 Stereo Mix Export MAIN MIX L/R bus files [MAIN MIX L/R bus MTR Tracks 23/24] can be converted to a single stereo [WAV] file. Converted stereo [WAV] files are saved in the MUSIC folder. OM page 48: Playing [previously recorded] WAV files ([Menu] SD PLAY mode) WAV files [placed] in the MUSIC folder on an SD card can be played back...Playback signal is sent from channels 21 and 22 [the Bluetooth interface channels].
