3 INTRODUCTION TO STUDIO MIX LIBRARIES The OwnHammer Studio Mix Libraries have a specific goal in mind to implement mic choice, mic placement, and mic amplification in a way that is most suitable to a specific cabinet and the types of speakers, amps, and tones most commonly associated with it. Once the configuration is set, it is static for all speakers loaded in that specific cabinet. Both traditional and non-traditional speakers to this configuration then provide the variable shades of sound beyond mic choice and mixed blending. With different cabinets comes the possibility for changes to the configuration, and such are the OwnHammer Studio Mix Libraries. 412-GTR MAR-CB THE CABINET The 412-GTR MAR-CB is based on a late 1970 s Marshall 1960B 4x12 guitar cabinet. This specific model of cabinet is often referred to as a checkerboard cabinet due to the type of grill cloth used. THE MICS CND 70 Based on a close mic d Microtech Gefell UMT70S large diaphragm condenser microphone. DYN 57 Based on a close mic d Shure SM57 dynamic microphone. DYN 421 Based on a close mic d Sennheiser MD421 dynamic microphone. RBN 121 Based on a close mic d Royer R121 ribbon microphone. ROOM Based on an ambiently placed Microtech Gefell UMT70S large diaphragm condenser microphone. THE MIXES Please Note none of the mixes in this library contain the Room capture, which can add dimension and bark to low and mid gain tones respectively. Adding this ambient character can pull a guitar track back from the forefront of the sonic array and is why it is left to the user to blend in to taste. Page 3

NEBULA FORMAT FILES NEBULA VERSION REQUIREMENT Nebula format files are created with and intended for version of Nebula 2 or 3 (commercial version only) and higher. These programs will not work with the Free or LE (such as Nebula CM, etc) derivatives. If using Nebula 2, it is a design of that platform to not display the text or slider value above the faders this is a Nebula 3 value added feature and not related to the OwnHammer implementation. INSTALLING THE PROGRAM AND VECTOR FILES After extracting the archive contents, to install the Programs, copy all of the.n2p files from:..\ownhammer_impulse_responses\%library NAME%\Nebula\Programs and paste them to:..\nebulatemprepository\programs To install the Vectors, copy the.n2v files from:..\ownhammer_impulse_responses\%library NAME%\Nebula\Vectors and paste them to:..\nebulatemprepository\vectors EDITING THE DICTIONARY FILE After extracting the archive content, look for the following file:..\ownhammer_impulse_responses\%library NAME%\Nebula\Dictionary_Tags.txt Contained within this file are tags that can be added to the Rom.xml file in your..\nebulatemprepository\dictionaries directory. XML files typically use character encoding that basic text editors are not capable of compiling. Editing and saving xml files in ASCII text encoding can break them, and is not recommended in most cases. For that reason, when editing xml files we use and recommend the Firstobject XML Editor found at This is a free, lightweight xml editor that refrains from implementing overcomplicated organizational schemes, therefore resembling a basic text editor and will auto detect the encoding of the Rom.xml and save it properly.

7 Altering the tag definitions will allow for functional menu browsing within the Nebula GUI, as it will allow the category descriptor to be presented in recognizable terms. EDITING THE RATE CONVERSION VALUE If using these programs in sessions with sample rates other than 96 khz, the RATECONVERSION tag will need to be edited in your plugin s xml parameter control file. Editing the RATE CNV parameter on the MAST page of the plugin GUI is only a temporary fix, the following will ensure you will not need to repeat editing that value every time you use Nebula. First, browse to wherever your Nebula2, Nebula2 Reverb, Nebula3, and/or Nebula3 Reverb plugins have been installed. Along with each of the above.dll files are.xml files. Using an XML EDITOR ONLY (such as the one mentioned in the previous section), open and edit each of the.xml files. In each will be a value most of the way down the file with the following tags: <RATECONVERSION> </RATECONVERSION> For the OwnHammer Nebula files to function properly in DAW sessions other than 96 khz, the number here needs to have a value of (one million). This number could fluctuate depending on your computer hardware and subsequent processing power. If the conversion is working properly, when you load a program you will see the following on the main progam window: FRT: > Hz If the value of the RATECONVERSION parameter is not high enough, in addition to bad sound this will read: FRT: > Hz <- In this case, the <- at the end will be blinking. After adjusting this parameter you may also need to delete and readd or reload Nebula instances in existing DAW sessions. PROGRAMS MENU LOCATION Once the files have been installed and the dictionary tags are populated properly, look for the OwnHammer Speaker Cabinets to appear in the OH Cabs MIX (OHCM) section of the pull down menu, which is populated by clicking on the large Init text near the top left corner of a freshly loaded Nebula instance. GUI SLIDER CONTROL Upon loading a program from this library, there are three controls for the user to adjust to taste: POWER This slider allows you to choose between the 3 different kinds of power amps that drive the speakers in this library. The value is labeled as Tube as the values translate accordingly: 2 = Tube 2 (5881) 1 = Tube 1 (6V6) 0 = Solid State Page 7

8 G-LVL The Gain Level slider boosts the input signal flowing into the Nebula plugin while simultaneously lowering the output. This is typically most useful in programs that are sampled dynamically, which this library is not. However, the slider still has an effect on harmonic levels, and is included thusly. Care must be taken with this control. Nebula is great at many things, but clipping distortion is not one of them. When setting this slider, listen for overload characteristics such as unnatural bass spikes, garbled audio, and transient spike chirps. Whenever you hear one of these negative artifacts, lower the slider 3-6 db below where you first hear the sound at a point when the audio passing through it is the loudest in the given track. Since it is impossible to predict what kind of audio will be used with these programs and the volume passed through them, the slider is set at 0.00 by default and it is up to the user to gauge the appropriate value for their material. For those familiar with Nebula, this slider is the same as GDRIVE. H-DST The Harmonic Distortion slider raises or lowers the volume level of the harmonic distortion kernels (kernels 2 through 8) relative to the fundamental (kernel 1). This allows one to go beyond the natural state of the hardware and create unique sounds to taste. It is possible to overload this function as well, so listen for unnatural fizzy distorting sounds to know that you ve pushed the level too far. For those familiar with Nebula, this slider is the same as DRIVE. WAV FILES Files in the Wav folder contain files in.wav format for use in any convolution reverb loader, be it DAW hosts or external hardware devices. These files are formatted in 44.1 khz, 48 khz, 88.2 khz, and 96 khz sample rates in mono and stereo (dual mono) channel options for greater compatibility potential. In addition to the full 500 millisecond files are shorter 200 millisecond files located in the..\wav\truncated directory. These will be useful for IR loaders that impose a sample length limit, and potentially help with CPU usage on less powerful systems or where track and instance counts are high. For information concerning loading of these files into the host of your choice, please refer to their website or documentation. FRACTAL AUDIO SYSEX FILES Files in the Axe-Fx folder contain files in.syx format for use with the Fractal Audio Axe-Fx Standard and Axe-Fx Ultra. Files in the Axe-Fx-II folder contain files in.syx format for use with the Fractal Audio Axe-Fx II. These files are derived from the 48 khz Mono.wav files, which are minimum phase aligned so as to be time and phase coherent if mixing them with stock FAS cab IR s. All Axe-Fx files were converted using the final version of aomdsp. All Axe-Fx II files were converted using the most recent version (at the time of library creation) of Cab Lab. For information concerning loading of these files into FAS devices, please refer to the documentation and forum at Page 8

9 KEMPER PROFILING AMP FILES Files in the Kemper folder contain files in.kipr format for use with the Kemper Profiling Amp. These files were created using Kemper s Cab Maker application to convert the minimum phase aligned 44.1 khz Mono.wav files. For information concerning loading of these files into KPA devices, please refer to the documentation and forum at Page 9
